I would like to replace the default 2048 bit host key generated when installing OpenSSH or starting it the first time with one of 4096 bit length.
This leads to two questions:
- Does OpenSSH allow running with a 4096 bit RSA host key (for SSH2 obviously)?
- How can
ssh-keygenbe convinced not to prompt for a passphrase?
The version of OpenSSH I am running is 6.6p1.
