Hi there, Brad Handy,

On 13 November 2000, I received the following message from you regarding
"PGP and GPG"

BH> Can PGP encrypted messages be decrypted by GPG and vice versa?  If both are
BH> decrypt the other then what versions of PGP can GPG understand and what

Under Windows, PGP 5.x to 7.0 messages can be decrypted by GnuPG 1.0.4,
but PGP 2.6.x messages cannot.  If GnuPG (Windows version) is used to
generate a key which will encrypt a message, PGP cannot decrypt it.
However, if GnuPG is used to encrypt with a key generated by PGP 5.x
to 7.0, the message can be decrypted by PGP 7.0 and may be decrypted
by PGP 6.x.x  I am not sure about PGP 5.x.x, as I have not had to deal
with messages using keys generated by PGP 5.x AFAIK.

GnuPG will deal easily with Twofish encryption as used in PGP 7.0

Broadly speaking, GnuPG is a better encryption/verification program
than PGP IMHO, but in Windows it does not yet have the GUI that PGP
does, nor keyserver support.

Please PGP/GnuPG sign mail for verification and encrypt for internet security
