Git is a distributed version control system, which means you can work locally,
then share or push your changes to a server. In this case, the server you push to is GitLab.

GitLab uses the SSH protocol to securely communicate with Git.
When you use SSH keys to authenticate to the GitLab remote server,
you don’t need to supply your username and password each time.

What are SSH keys

SSH uses two keys, a public key and a private key.

• The public key can be distributed.
• The private key should be protected.

It is not possible to reveal confidential data by uploading your public key. When you need to copy or upload your SSH public key, make sure you do not accidentally copy or upload your private key instead.

You can use your private key to sign commits,
which makes your use of GitLab and your data even more secure.
This signature then can be verified by anyone using your public key.

For details, see Asymmetric cryptography, also known as public-key cryptography.

Prerequisites

To use SSH to communicate with GitLab, you need:

• The OpenSSH client, which comes pre-installed on GNU/Linux, macOS, and Windows 10.
• SSH version 6.5 or later. Earlier versions used an MD5 signature, which is not secure.

To view the version of SSH installed on your system, run ssh -V.

Supported SSH key types

To communicate with GitLab, you can use the following SSH key types:

• ED25519
• ED25519_SK (Available in GitLab 14.8 and later.)
• ECDSA_SK (Available in GitLab 14.8 and later.)
• RSA
• DSA (Deprecated in GitLab 11.0.)
• ECDSA (As noted in Practical Cryptography With Go, the security issues related to DSA also apply to ECDSA.)

Administrators can restrict which keys are permitted and their minimum lengths.

ED25519 SSH keys

The book Practical Cryptography With Go
suggests that ED25519 keys are more secure and performant than RSA keys.

OpenSSH 6.5 introduced ED25519 SSH keys in 2014, and they should be available on most
operating systems.

ED25519_SK SSH keys

To use ED25519_SK SSH keys on GitLab, your local client and GitLab server
must have OpenSSH 8.2 or later installed.

ECDSA_SK SSH keys

To use ECDSA_SK SSH keys on GitLab, your local client and GitLab server
must have OpenSSH 8.2 or later installed.

RSA SSH keys

Maximum RSA key length changed in GitLab 16.3.

Available documentation suggests ED25519 is more secure than RSA.

If you use an RSA key, the US National Institute of Standards and Technology in
Publication 800-57 Part 3 (PDF)
recommends a key size of at least 2048 bits. Due to limitations in Go,
RSA keys cannot exceed 8192 bits.

The default key size depends on your version of ssh-keygen.
Review the man page for your installed ssh-keygen command for details.

See if you have an existing SSH key pair

Before you create a key pair, see if a key pair already exists.

1. Go to your home directory.
2. Go to the .ssh/ subdirectory. If the .ssh/ subdirectory doesn’t exist,
   you are either not in the home directory, or you haven’t used ssh before.
   In the latter case, you need to generate an SSH key pair.

3. See if a file with one of the following formats exists:

   Algorithm	Public key	Private key
   ED25519 (preferred)	id_ed25519.pub	id_ed25519
   ED25519_SK	id_ed25519_sk.pub	id_ed25519_sk
   ECDSA_SK	id_ecdsa_sk.pub	id_ecdsa_sk
   RSA (at least 2048-bit key size)	id_rsa.pub	id_rsa
   DSA (deprecated)	id_dsa.pub	id_dsa
   ECDSA	id_ecdsa.pub	id_ecdsa

Generate an SSH key pair

If you do not have an existing SSH key pair, generate a new one:

1. Open a terminal.

2. Run ssh-keygen -t followed by the key type and an optional comment.
   This comment is included in the .pub file that’s created.
   You may want to use an email address for the comment.

   For example, for ED25519:

   ssh-keygen -t ed25519 -C "<comment>"
   

   For 2048-bit RSA:

   ssh-keygen -t rsa -b 2048 -C "<comment>"
   

3. Press Enter. Output similar to the following is displayed:

   Generating public/private ed25519 key pair.
   Enter file in which to save the key (/home/user/.ssh/id_ed25519):
   

4. Accept the suggested filename and directory, unless you are generating a deploy key
   or want to save in a specific directory where you store other keys.

   You can also dedicate the SSH key pair to a specific host.

5. Specify a passphrase:

   Enter passphrase (empty for no passphrase):
   Enter same passphrase again:
   

   A confirmation is displayed, including information about where your files are stored.

A public and private key are generated. Add the public SSH key to your GitLab account
and keep the private key secure.

Configure SSH to point to a different directory

If you did not save your SSH key pair in the default directory,
configure your SSH client to point to the directory where the private key is stored.

1. Open a terminal and run this command:

   eval $(ssh-agent -s)
   ssh-add <directory to private SSH key>
   

2. Save these settings in the ~/.ssh/config file. For example:

   # GitLab.com
   Host gitlab.com
     PreferredAuthentications publickey
     IdentityFile ~/.ssh/gitlab_com_rsa
   
   # Private GitLab instance
   Host gitlab.company.com
     PreferredAuthentications publickey
     IdentityFile ~/.ssh/example_com_rsa
   

For more information on these settings, see the man ssh_config page in the SSH configuration manual.

Public SSH keys must be unique to GitLab because they bind to your account.
Your SSH key is the only identifier you have when you push code with SSH.
It must uniquely map to a single user.

Update your SSH key passphrase

You can update the passphrase for your SSH key:

1. Open a terminal and run this command:

   ssh-keygen -p -f /path/to/ssh_key
   

2. At the prompts, enter the passphrase and then press Enter.

Upgrade your RSA key pair to a more secure format

If your version of OpenSSH is between 6.5 and 7.8, you can save your private
RSA SSH keys in a more secure OpenSSH format by opening a terminal and running
this command:

ssh-keygen -o -f ~/.ssh/id_rsa

Alternatively, you can generate a new RSA key with the more secure encryption format with
the following command:

ssh-keygen -o -t rsa -b 4096 -C "<comment>"

Generate an SSH key pair for a FIDO2 hardware security key

To generate ED25519_SK or ECDSA_SK SSH keys, you must use OpenSSH 8.2 or later:

1. Insert a hardware security key into your computer.
2. Open a terminal.

3. Run ssh-keygen -t followed by the key type and an optional comment.
   This comment is included in the .pub file that’s created.
   You may want to use an email address for the comment.

   For example, for ED25519_SK:

   ssh-keygen -t ed25519-sk -C "<comment>"
   

   For ECDSA_SK:

   ssh-keygen -t ecdsa-sk -C "<comment>"
   

   If your security key supports FIDO2 resident keys, you can enable this when
   creating your SSH key:

   ssh-keygen -t ed25519-sk -O resident -C "<comment>"
   

   -O resident indicates that the key should be stored on the FIDO authenticator itself.
   Resident key is easier to import to a new computer because it can be loaded directly
   from the security key by ssh-add -K
   or ssh-keygen -K.

4. Press Enter. Output similar to the following is displayed:

   Generating public/private ed25519-sk key pair.
   You may need to touch your authenticator to authorize key generation.
   

5. Touch the button on the hardware security key.

6. Accept the suggested filename and directory:

   Enter file in which to save the key (/home/user/.ssh/id_ed25519_sk):
   

7. Specify a passphrase:

   Enter passphrase (empty for no passphrase):
   Enter same passphrase again:
   

   A confirmation is displayed, including information about where your files are stored.

A public and private key are generated.
Add the public SSH key to your GitLab account.

Generate an SSH key pair with a password manager

Generate an SSH key pair with 1Password

You can use 1Password and the 1Password browser extension to either:

• Automatically generate a new SSH key.
• Use an existing SSH in your 1Password vault to authenticate with GitLab.

1. Sign in to GitLab.
2. On the left sidebar, select your avatar.
3. Select Edit profile.
4. On the left sidebar, select SSH Keys.
5. Select Key, and you should see the 1Password helper appear.
6. Select the 1Password icon and unlock 1Password.
7. You can then select Create SSH Key or select an existing SSH key to fill in the public key.
8. In the Title box, type a description, like Work Laptop or
   Home Workstation.
9. Optional. Select the Usage type of the key. It can be used either for Authentication or Signing or both. Authentication & Signing is the default value.
10. Optional. Update Expiration date to modify the default expiration date.
11. Select Add key.

For more information about using 1Password with SSH keys, see the 1Password documentation.

Add an SSH key to your GitLab account

To use SSH with GitLab, copy your public key to your GitLab account:

1. Copy the contents of your public key file. You can do this manually or use a script.
   For example, to copy an ED25519 key to the clipboard:

   macOS

   tr -d '\n' < ~/.ssh/id_ed25519.pub | pbcopy
   

   Linux (requires the xclip package)

   xclip -sel clip < ~/.ssh/id_ed25519.pub
   

   Git Bash on Windows

   cat ~/.ssh/id_ed25519.pub | clip
   

   Replace id_ed25519.pub with your filename. For example, use id_rsa.pub for RSA.

2. Sign in to GitLab.
3. On the left sidebar, select your avatar.
4. Select Edit profile.
5. On the left sidebar, select SSH Keys.
6. Select Add new key.
7. In the Key box, paste the contents of your public key.
   If you manually copied the key, make sure you copy the entire key,
   which starts with ssh-rsa, ssh-dss, ecdsa-sha2-nistp256, ecdsa-sha2-nistp384, ecdsa-sha2-nistp521,
   ssh-ed25519, sk-ecdsa-sha2-nistp256@openssh.com, or sk-ssh-ed25519@openssh.com, and may end with a comment.
8. In the Title box, type a description, like Work Laptop or
   Home Workstation.
9. Optional. Select the Usage type of the key. It can be used either for Authentication or Signing or both. Authentication & Signing is the default value.
10. Optional. Update Expiration date to modify the default expiration date.
    In:
    • GitLab 13.12 and earlier, the expiration date is informational only. It doesn’t prevent
      you from using the key. Administrators can view expiration dates and use them for
      guidance when deleting keys.
    • GitLab checks all SSH keys at 02:00 AM UTC every day. It emails an expiration notice for all SSH keys that expire on the current date. (Introduced in GitLab 13.11.)
    • GitLab checks all SSH keys at 01:00 AM UTC every day. It emails an expiration notice for all SSH keys that are scheduled to expire seven days from now. (Introduced in GitLab 13.11.)
11. Select Add key.

Verify that you can connect

Verify that your SSH key was added correctly.

The following commands use the example hostname gitlab.example.com. Replace this example hostname with your GitLab instance’s hostname, for example, git@gitlab.com.

1. To ensure you’re connecting to the correct server, check the server’s SSH host keys fingerprint. For:
   • GitLab.com, see the SSH host keys fingerprints documentation.
   • GitLab.com or another GitLab instance, see gitlab.example.com/help/instance_configuration#ssh-host-keys-fingerprints where gitlab.example.com is gitlab.com (for
     GitLab.com) or the address of the GitLab instance.

2. Open a terminal and run this command, replacing gitlab.example.com with your
   GitLab instance URL:

   ssh -T git@gitlab.example.com
   

3. If this is the first time you connect, you should verify the
   authenticity of the GitLab host. If you see a message like:

   The authenticity of host 'gitlab.example.com (35.231.145.151)' can't be established.
   ECDSA key fingerprint is SHA256:HbW3g8zUjNSksFbqTiUWPWg2Bq1x8xdGUrliXFzSnUw.
   Are you sure you want to continue connecting (yes/no)? yes
   Warning: Permanently added 'gitlab.example.com' (ECDSA) to the list of known hosts.
   

   Type yes and press Enter.

4. Run the ssh -T git@gitlab.example.com command again. You should receive a Welcome to GitLab, @username! message.

If the welcome message doesn’t appear, you can troubleshoot by running ssh
in verbose mode:

ssh -Tvvv git@gitlab.example.com

Use different keys for different repositories

You can use a different key for each repository.

Open a terminal and run this command:

git config core.sshCommand "ssh -o IdentitiesOnly=yes -i ~/.ssh/private-key-filename-for-this-repository -F /dev/null"

This command does not use the SSH Agent and requires Git 2.10 or later. For more information
on ssh command options, see the man pages for both ssh and ssh_config.

View your account’s SSH keys

1. Sign in to GitLab.
2. On the left sidebar, select your avatar.
3. Select Edit profile.
4. On the left sidebar, select SSH Keys.

Your existing SSH keys are listed at the bottom of the page. The information includes:

• The key’s:
  • Name.
  • Public fingerprint.
  • Expiry date.
  • Permitted usage types.
• The time a key was last used. On GitLab.com this value is unavailable, and you are unable to see if or when an SSH key has been used. For more information, see issue 324764.

Select Delete to permanently delete an SSH key.

Use different accounts on a single GitLab instance

You can use multiple accounts to connect to a single instance of GitLab. You
can do this by using the command in the previous topic.
However, even if you set IdentitiesOnly to yes, you cannot sign in if an
IdentityFile exists outside of a Host block.

Instead, you can assign aliases to hosts in the ~/.ssh/config file.

• For the Host, use an alias like user_1.gitlab.com and
  user_2.gitlab.com. Advanced configurations
  are more difficult to maintain, and these strings are easier to
  understand when you use tools like git remote.
• For the IdentityFile, use the path the private key.

# User1 Account Identity
Host <user_1.gitlab.com>
  Hostname gitlab.com
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/<example_ssh_key1>

# User2 Account Identity
Host <user_2.gitlab.com>
  Hostname gitlab.com
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/<example_ssh_key2>

Now, to clone a repository for user_1, use user_1.gitlab.com in the git clone command:

git clone git@<user_1.gitlab.com>:gitlab-org/gitlab.git

To update a previously-cloned repository that is aliased as origin:

git remote set-url origin git@<user_1.gitlab.com>:gitlab-org/gitlab.git

Configure two-factor authentication (2FA)

You can set up two-factor authentication (2FA) for
Git over SSH. We recommend using
ED25519_SK or ECDSA_SK SSH keys.

Use EGit on Eclipse

If you are using EGit, you can add your SSH key to Eclipse.

Use SSH on Microsoft Windows

If you’re running Windows 10, you can either use the Windows Subsystem for Linux (WSL)
with WSL 2 which
has both git and ssh preinstalled, or install Git for Windows to
use SSH through PowerShell.

The SSH key generated in WSL is not directly available for Git for Windows, and vice versa,
as both have a different home directory:

• WSL: /home/<user>
• Git for Windows: C:\Users\<user>

You can either copy over the .ssh/ directory to use the same key, or generate a key in each environment.

If you’re running Windows 11 and using OpenSSH for Windows, ensure the HOME
environment variable is set correctly. Otherwise, your private SSH key might not be found.

Alternative tools include:

• Cygwin
• PuttyGen

Overriding SSH settings on the GitLab server

GitLab integrates with the system-installed SSH daemon and designates a user
(typically named git) through which all access requests are handled. Users
who connect to the GitLab server over SSH are identified by their SSH key instead
of their username.

SSH client operations performed on the GitLab server are executed as this
user. You can modify this SSH configuration. For example, you can specify
a private SSH key for this user to use for authentication requests. However, this practice
is not supported and is strongly discouraged as it presents significant
security risks.

GitLab checks for this condition, and directs you
to this section if your server is configured this way. For example:

$ gitlab-rake gitlab:check

Git user has default SSH configuration? ... no
  Try fixing it:
  mkdir ~/gitlab-check-backup-1504540051
  sudo mv /var/lib/git/.ssh/id_rsa ~/gitlab-check-backup-1504540051
  sudo mv /var/lib/git/.ssh/id_rsa.pub ~/gitlab-check-backup-1504540051
  For more information see:
  doc/user/ssh.md#overriding-ssh-settings-on-the-gitlab-server
  Please fix the error above and rerun the checks.

Remove the custom configuration as soon as you can. These customizations
are explicitly not supported and may stop working at any time.

Troubleshooting

TLS: server sent certificate containing RSA key larger than 8192 bits

In GitLab 16.3 and later, Go limits RSA keys to a maximum of 8192 bits.
To check the length of a key:

openssl rsa -in <your-key-file> -text -noout | grep "Key:"

Replace any key longer than 8192 bits with a shorter key.

Password prompt with git clone

When you run git clone, you may be prompted for a password, like git@gitlab.example.com's password:.
This indicates that something is wrong with your SSH setup.

• Ensure that you generated your SSH key pair correctly and added the public SSH
  key to your GitLab profile.
• Try to manually register your private SSH key by using ssh-agent.
• Try to debug the connection by running ssh -Tv git@example.com.
  Replace example.com with your GitLab URL.
• Ensure you followed all the instructions in Use SSH on Microsoft Windows.

Could not resolve hostname error

You may receive the following error when verifying that you can connect:

ssh: Could not resolve hostname gitlab.example.com: nodename nor servname provided, or not known

If you receive this error, restart your terminal and try the command again.

Key enrollment failed: invalid format error

You may receive the following error when generating an SSH key pair for a FIDO2 hardware security key:

Key enrollment failed: invalid format

You can troubleshoot this by trying the following:

• Run the ssh-keygen command using sudo.
• Verify your FIDO2 hardware security key supports
  the key type provided.
• Verify the version of OpenSSH is 8.2 or greater by
  running ssh -V.

Introduction

Git connects to remotes by default via HTTPS, which requires you to enter your login and password every time you run a command like Git pull or git push, using the SSH protocol. You may connect to servers and authenticate to access their services. The three services listed allow Git to connect through SSH rather than HTTPS. Using public-key encryption eliminates the need to type a login and password for each Git command.

Make sure a Git is installed

Make sure Git is installed before you start. Run the following command in your Windows terminal to see if Git is installed on your computer:

git --version

Install Git

To install Git, you can download the latest version from the official Git website. You can also install Git using Chocolatey or Winget package manager.

Test connecting via SSH

Before utilizing SSH with Git, GitHub, GitLab, and Bitbucket allow you to verify whether the connection has been set up successfully.

GitHub Test Connecting via SSH

Open the terminal once you’ve added your SSH key to your GitHub account and type:

ssh -T git@github.com

If you’re connecting to GitHub over SSH for the first time, the SSH client will ask if you trust the GitHub server’s public key:

The authenticity of host 'github.com (140.82.113.4)' can't be established.
RSA key fingerprint is SHA256:a5d6c20b1790b4c144b9d26c9b201bbee3797aa010f2701c09c1b3a6262d2c02.
Are you sure you want to continue connecting (yes/no)?

Press Enter after typing yes. GitHub has been added to the list of trustworthy hosts in the SSH client:

Warning: Permanently added 'github.com,140.82.113.4' (RSA) to the list of known hosts.

You won’t be asked about GitHub’s public key again once you’ve added it to the list of known hosts.

The server notifies you that you have successfully authenticated and ends the connection: Because this remote access through SSH is offered by GitHub only for testing purposes and not for practical usage, the server informs you that you have successfully authenticated and terminates the connection:

Hi YOUR_USER_NAME! You've successfully authenticated, but GitHub does not provide shell access.

If you passed the test, you may now utilize SSH with GitHub.

The entire interaction should look something like this:

ssh -T git@github.com

The authenticity of host 'github.com (140.82.113.4)' can't be established.
RSA key fingerprint is SHA256:a5d6c20b1790b4c144b9d26c9b201bbee3797aa010f2701c09c1b3a6262d2c02.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'github.com,140.82.113.4' (RSA) to the list of known hosts.

YOUR_USER_NAME@YOUR_HOST_NAME:~>

GitLab Test Connecting via SSH

The test is pretty similar if you’ve added your SSH key to your GitLab account:

ssh -T git@gitlab.com

The authenticity of host 'gitlab.com (35.231.145.151)' can't be established.
ECDSA key fingerprint is SHA256:4ac7a7fd4296d5e6267c9188346375ff78f6097a802e83c0feaf25277c9e70cc.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'gitlab.com,35.231.145.151' (ECDSA) to the list of known hosts.
Welcome to GitLab, @YOUR_USER_NAME!

If you passed the test, you may now utilize SSH with GitLab.

Bitbucket Test Connecting via SSH

The test is pretty similar if you’ve added your SSH key to your Bitbucket account:

SSH-ключи представляют собой аутентификационные данные, которые позволяют безопасно соединяться с удаленным сервером. Если вы работаете с GitLab, создание SSH-ключей является важным шагом, чтобы обеспечить безопасность и защиту вашего доступа к репозиториям.

В данной подробной инструкции мы рассмотрим, как создать SSH-ключи в среде Windows для использования с GitLab. Мы покажем каждый шаг снабженный подробными объяснениями, чтобы вы смогли легко и без проблем создать свои SSH-ключи на своем компьютере.

Процесс создания SSH-ключей в Windows включает в себя несколько этапов. Сначала вам нужно установить Git Bash, затем сгенерировать SSH-ключи, а затем скопировать открытый ключ и добавить его в ваш аккаунт GitLab. Мы рассмотрим каждый из этих шагов и дадим вам все необходимые инструкции для успешного выполнения этих действий.

Создание SSH-ключей в Windows для GitLab может показаться сложной задачей, однако, следуя этой подробной инструкции, вы сможете без проблем сгенерировать свои аутентификационные данные и наслаждаться безопасным доступом к вашим репозиториям на GitLab.

Почему нужно использовать SSH-ключи при работе с GitLab и Windows?

• Безопасность: SSH-ключи гарантируют безопасность вашего подключения, так как они используют асимметричное шифрование для передачи данных.
• Удобство: после настройки SSH-ключей, вы можете подключаться к GitLab без необходимости вводить пароль каждый раз.
• Автоматическая аутентификация: при использовании SSH-ключей, GitLab может автоматически аутентифицировать вас и проверить, что вы имеете право получить доступ к нужным репозиториям.
• Доступ к приватным репозиториям: использование SSH-ключей позволяет вам иметь доступ к приватным репозиториям без необходимости каждый раз вводить учётные данные.

В целом, использование SSH-ключей при работе с GitLab и Windows делает процесс авторизации и подключения более безопасным и удобным. Наша подробная инструкция поможет вам создать SSH-ключи и настроить их для работы с GitLab на вашей Windows-машине.

Как установить Git Bash в Windows для работы с SSH-ключами

Git Bash представляет собой эмулятор командной строки, предназначенный для работы с Git и другими инструментами командной строки в системе Windows. Он позволяет выполнять те же самые команды, которые можно использовать в Linux или Mac, что упрощает работу с Git и SSH-ключами.

Вот пошаговая инструкция по установке Git Bash в Windows:

1. Перейдите на официальный сайт Git по адресу https://git-scm.com/.
2. Нажмите на кнопку «Скачать», чтобы загрузить установочный файл Git для Windows.
3. Откройте загруженный файл и запустите процесс установки.
4. Выберите папку для установки Git, оставив значение по умолчанию, и нажмите «Далее».
5. Выберите компоненты для установки, оставив значения по умолчанию, и нажмите «Далее».
6. Выберите редактор по умолчанию для Git, оставив значение по умолчанию, и нажмите «Далее».
7. Выберите пункт «Use Git from Git Bash only», чтобы использовать Git Bash вместо стандартного командного интерфейса Windows, и нажмите «Далее».
8. Выберите пункт «Use the OpenSSL library», чтобы использовать библиотеку OpenSSL для шифрования данных, и нажмите «Далее».
9. Выберите пункт «Checkout Windows-style, commit Unix-style line endings», чтобы привести окончания строк к стилю Windows при проверке файлов, и нажмите «Далее».
10. Выберите пункт «Enable file system caching» для улучшения производительности работы с Git, и нажмите «Далее».
11. Выберите пункт «Enable Git Credential Manager», чтобы использовать менеджер учетных данных Git для хранения ваших учетных данных, и нажмите «Далее».
12. Выберите пункт «Enable symbolic links», чтобы включить поддержку символических ссылок, и нажмите «Далее».
13. Выберите пункт «Enable Git Bash Here», чтобы добавить контекстное меню «Git Bash Here» в проводнике Windows, и нажмите «Далее».
14. Выберите пункт «Enable Git GUI Here», чтобы добавить контекстное меню «Git GUI Here» в проводнике Windows, и нажмите «Далее».
15. Выберите пункт «Default (fast-forward or merge)», чтобы выбрать стратегию по умолчанию для слияния веток в Git, и нажмите «Далее».
16. Нажмите «Установить», чтобы начать процесс установки Git.
17. Подождите, пока процесс установки завершится.
18. Нажмите «Завершить», чтобы закрыть установщик Git.

После установки Git Bash будет доступен в меню «Пуск» или на рабочем столе. Вы можете открыть его и начать работу с Git и SSH-ключами в командной строке.

Генерация SSH-ключей в Git Bash для работы с GitLab

Шаг 1. Установите Git Bash, если у вас его еще нет. Вы можете скачать его с официального сайта Git (https://git-scm.com/downloads) и выполнить установку следуя инструкциям.

Шаг 2. Откройте Git Bash из меню Пуск или запустив ярлык на рабочем столе. Этот терминал будет использоваться для генерации и настройки SSH-ключей.

Шаг 3. Введите следующую команду в Git Bash, чтобы сгенерировать новую пару SSH-ключей:

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

Вместо «your_email@example.com» введите вашу электронную почту, которую используете на GitLab.

Шаг 4. Git Bash спросит вас, в какую директорию сохранить ключи. Вы можете выбрать место, где вам удобно сохранить ключи, или оставить значение по умолчанию, просто нажав Enter.

Шаг 5. Git Bash также спросит вас, должны ли ключи быть защищены паролем. Если вы хотите, чтобы каждый раз при использовании ключа вас спрашивали пароль, введите пароль дважды. Если вы не хотите устанавливать пароль, просто оставьте поле пустым и нажмите Enter.

Шаг 6. После успешной генерации ключей, Git Bash покажет вам путь к вашему созданному ключу, например: /c/Users/your_username/.ssh/id_rsa. Сохраните этот путь, так как он понадобится нам далее.

Шаг 7. Откройте содержимое вашего публичного ключа, который был сгенерирован в предыдущем шаге. В Git Bash введите команду:

cat ~/.ssh/id_rsa.pub

Скопируйте отображаемый ключ, он будет выглядеть примерно так:

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAACAQDhbnVzDzIszws7qme...

Шаг 8. Теперь вам необходимо добавить свой публичный ключ в настройки GitLab. Перейдите в настройки вашего профиля в GitLab, затем в режиме чтения-записи скопируйте ваш публичный ключ в поле «SSH Keys» и сохраните изменения.

Готово! Теперь вы можете использовать SSH-ключи для работы с GitLab на своем компьютере.
