I have an rsa 2048 key with a 65537 public exponent, but the ssh-agent refuses to sign it.

signing with ssh-rsa is unsupported; SHA-1 may be insecure is the message in the log for the ssh-agent. openssl rsa -text -in ./id_rsa |grep publ writing RSA key publicExponent: 65537 (0x10001)...

I found this comment on another thread after posting this .. and it may be my problem..

"Do you see anything appear in the logs when you invoke the SSH command? On macOS: ~/Library/Group Containers/2BUA8C4S2C.com.1password/Library/Application Support/1Password/Data/logs/1Password_rCURRENT.log

It could be that the EC2 instance only supports SHA1 signatures for RSA keys. This is something that the SSH agent doesn't support at the moment. If that's the case, you can consider switching to Ed25519 keys, or upgrading OpenSSH on your server so that it supports more modern algorithms.

For Azure DevOps, that's not an option unfortunately. So be on the lookout for updates! (Either from our side or from Azure's side)
