How do i generate ECDSA key in CentOS ? and then, How do i use it with OpenSSH in CentOS ? (CentOS v6.3 , v6.4)
You'll have to install OpenSSH release 5.7 or newer. Standard CentOS 6 still ships with OpenSSH 5.3 which doesn't know about ECDSA yet.
FYI, PuTTY doesn't support ECDSA either. You might be better off staying with tried-and-true RSA.
