Sorry for the late reply.

I cannot find anything running on port 3322, but indeed changing the 
base to 94 makes the test pass.

However, unless the tests are executed with the insecure LEGACY crypto 
policy, they still fail with:
[...]

regress/failed-ssh.log then contains lines like:
debug1: libcrypto: 'error:03000098:digital envelope routines::invalid 
digest:crypto/evp/m_sigver.c:265:'
debug1: identity_sign: sshkey_sign: error in libcrypto: invalid digest
sign_and_send_pubkey: signing failed for RSA 
"/tmp/openssh/regress/cert_user_key_rsa": error in libcrypto

So my assumption would be this is due to some RSA-SHA1 usage or the like.

Is this intentional?

Thanks
