Not being very knowledgeable in the cypher world, are there any good online references that compare RSA vs DSS PGP? and why one would be better than the other?

thanks

If you use PGP 5.0 many people will refuse to read your messages and send them to you. They won't be able to decrypt your messages, verify your signatures, or use your keys. In general, using 5.0 just pisses people off. 5.0 is purposefully incompatable with all previous versions of PGP, they purposefully haven't released usable versions except for Windows and possibly Mac, they've purposefully broke any scripts and programs which invoke PGP, they purposefully made command-line versions of PGP many times more annoying to use, and PGP 5.x encrypts to a "CMR key" without having the decency to ask. Generally the PGP 5.x folks are being complete and total assholes about this entire thing and haven't done anything to improve the state of cryptography today and a whole lot to worsen it. Somebody recently posted a large rant about this titled "PGP 5.0: What were they thinking? (revisited)." CompatabilityMonger
