 ## Configuring SSH connections with RSA keys
 
 When users perform Git operations on {% data variables.location.product_location %} via SSH over port 22, the client can authenticate with an RSA key. The client may sign the attempt using the SHA-1 hash function. In this context, the SHA-1 hash function is no longer secure. For more information, see [SHA-1](https://en.wikipedia.org/wiki/SHA-1) on Wikipedia.
