I just made an RSA key and its size is 4096/4096. The cipher is IDEA and Hash is SHA-2 512. Is this stronger than my DH/DSS key with a cipher of CAST 4096/1024? Is RSA stronger than DH/DSS? I use PGP 9.0 and Kremlin with Blowfish. On PGP, I have the keys set at implicit trust and valid and the compression is ZLIB, but I am not sure what that means.
