4 years agoI 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)...

4 years agoperhaps an addition to the error message in the logs would be useful to point out that the ssh-server instance is too old and wont negotiate the newer rsa format.
