What did you do?

Connect via ssh to SFTP server.

Configuration code as follows:

  User: username,
  Auth: []ssh.AuthMethod{
    ssh.Password(password),
  },
  HostKeyCallback: ssh.InsecureIgnoreHostKey(),
})

No error

What did you see instead?

When I upgrade to the most recent commit of golang/crypto@ed5229d on the SSH package, I started getting errors when connecting to my SSH server using Password authentication.

Only tried against my existing server, but server version is SSH-2.0-1.82_sshlib Globalscape

Code errors out with ssh: handshake failed: ssh: parse error in message type 53

As soon as I roll back to the previous commit, it succeeds.
