If you use an RSA key, the US National Institute of Science and Technology in OpenSSH 6.5 introduced ED25519 SSH keys in 2014 and they should be available on mostĪvailable documentation suggests that ED25519 is more secure than RSA. Suggests that ED25519 keys are more secure and performant than RSA keys. ECDSA (As noted in Practical Cryptography With Go, the security issues related to DSA also apply to ECDSA.)Īdministrators can restrict which keys are permitted and their minimum lengths.To communicate with GitLab, you can use the following SSH key types: To view the version of SSH installed on your system, run ssh -V. Earlier versions used an MD5 signature, which is not secure. The OpenSSH client, which comes pre-installed on GNU/Linux, macOS, and Windows 10.To use SSH to communicate with GitLab, you need: You don’t need to supply your username and password each time. When you use SSH keys to authenticate to the GitLab remote server, GitLab uses the SSH protocol to securely communicate with Git. Then share or “push” your changes to a server. Git is a distributed version control system, which means you can work locally, Troubleshooting SSH connections GitLab and SSH keys.Overriding SSH settings on the GitLab server.Configure two-factor authentication (2FA).Use different accounts on a single GitLab instance.Use different keys for different repositories.
