DSA vs RSA

Sparks asked about the difference between DSA and RSA keys for SSH authentication.  Following is from a collection of notes over the years.  My sources have faded so you may want to do your own research if you planning on quoting any of the following:

• DSA generates keys faster, but verifies them slower,  than RSA


• DSA supposedly scales better


• DSA doesn't have the license restrictions that RSA has


• SSH protocol 1 only supports RSA


• SSH protocol 2 supports both RSA and DSA, though many implementations only include DSA support for protocol 2

Hope this answers your question, Sparks.
