Well SSH public keys aren't used for the actual session encryption, just
for authentication so that doesn't help when deciding between DSA & RSA 
keys.  The actual data session uses one of the ciphers 3des-cbc, 
aes128-cbc, aes192-cbc,  aes256-cbc, aes128-ctr, aes192-ctr, aes256-ctr,
arcfour128, arcfour256, arcfour, blowfish-cbc, and cast128-cbc
