compatibility issues

[Mark Brettin]

Got it.  I'm not exactly sure what the problem was but this is
what I did.

To recap:  

We have GnuPG 1.0.6 and we were not able to decrypt
PGP 7.0 files (no sigs, no IDEA, no BLOWFISH or TWOFISH).

What I did:

I downloaded PGP 7.0.3, installed it and generated a key pair.
I exported the PGP 7.0.3 key pair and then imported it into GnuPG

gpg --import --allow-secret-key-import New_Keys.asc

I then exported the public key for the new key pair and
passed it off to the customer.  Now I am decrypting his
messages.

I know this is a hack and I would much rather know what 
was wrong but it works.

Thanks all.

Regards,

Mark
