 The SSH Cryptosystem

On Lamp takes a look at the SSH Cryptosystem.

"Let's take a look at that output. You'll note that three separate key pairs were generated: one for rsa1, one for rsa, and one for dsa. You should recognize the RSA and DSA acronyms from the last article on cryptographic terms. But why so many key pairs? There are two versions of the SSH protocol, and OpenSSH supports them both. Not surprisingly, the rsa1 keypair is used by SSH version 1. You can see from the output that ssh2 (version 2) supports both RSA and DSA."
