My copy of PGP 5.0 seems to be completely compatible with 2.6 versions. This ... Of course your copy of PGP 5.0 is compatible with prior versions. I know this, you know this, and the anonymous author claiming otherwise knows
Some of the free 5.0 versions can use RSA keys, and some can't. Robert has the $5 RSA plugin, so his can. The Eudora version can't, and I think the MIT version can, or maybe it was the one on www.pgp.com. By "can't", I mean that it not only won't let you generate RSA keys, it also won't use existing RSA private keys from your old secring.pgp file; I don't know if it can encrypt to other people's RSA public keys or not. I found this very annoying a couple months ago when I was rebuilding my PGP from backups after a disk crash :-) The 5.0 version I'd been using before the crash was happily using my RSA keys, and the brand new Eudora version I used after the crash wouldn't take them, and wasn't very clear about why. One of the local PGP folks told me there was a difference, and loading the right version took care of the problem, and I don't remember encrypting to or validating from any RSA keys in between.
