Would it possible to add maximum size of RSA key length in man ssh-keygen.1 as ssh-keygen's limitation. in man ssh.1 as sshd's limitation. I think the maximum size for RSA key length in ssh-keygen is 16384 bits. And also the sshd support RSA key length up to 16384 bits. These information could be obvious for developer, but end user need to find them in man pages. Regards, Masanari Iida
