pgp confusion

[Shao Zhang <shao@cia.com.au>]

Hi,
	Is pgp5 backward compatible with pgp2? I have an email which is
	encrypted using pgp5 with my pubring generated by pgp2, but I
	could not seem to open it using pgp2.

	If I upgrade to pgp5, do I need to generate another keyring? If
	I do, should I use RSA or DSS for signing and encrypting email?
	If I don't need to generate another keyring, then I am having
	trouble to retrieve the keyring info using pgpk -l.

	Also, is gpg compatable with the both? Which one should I use?

	Thanks.
Shao.
