# How to Connect to Git via SSH
In addition to the HTTP/HTTPS protocols, Teamscale can communicate with Git repositories using Secure Shell (SSH).
When communicating with a Git repository over the SSH protocol, the Teamscale server may need to authenticate itself with a private key.
The private keys need to be stored by navigating to Admin > Settings > Git in Teamscale.
Each key consists of a configurable (unique) ID and the actual key material. The key can then be referred to in the configuration of the Git repository connector.
The key material is a Base64-encoded string enclosed by a header/footer pair like
BEGIN/END RSA PRIVATE KEY .
While Teamscale supports a wide range of SSH private key formats, it does not yet support the "new" OpenSSH private key format, which is enclosed by a header/footer pair of
BEGIN/END OPENSSH PRIVATE KEY.
If your private key is stored in this format, you can convert it to a format that Teamscale can handle like this:
Warning: This modifies the original private key file! You might want to create a backup beforehand.
ssh-keygen -p -e -m PEM -f $INPUT
puttygen $INPUT -O private-openssh -o $CONVERTED
