Ssh- keygen can create RSA keys for use by SSH protocol version 1 and DSA, ECDSA or RSA keys for use by SSH protocol version 2. If invoked without any arguments, ssh- keygen will generate an RSA key. According to the ssh- keygen man page, you have three choices for ECDSA key lengths: For ECDSA keys, the - b flag determines the key length by selecting from one of three elliptic curve sizes: 256, 384 or 521 bits.

This is a tutorial on its use, and covers several special use cases. I' m not a master on ssh keys but it seems that with the last openssh update on - current: Thu Jan 27 01: 53: n/ openssh- 5.
