Removing AES

[Steve Butler]

Don't need to generate a new key.  Just change the preferences on your
existing key.  Export it.  Give the new export out as your public key.

For example, the company's public key has been changed so it works great
with all versions of PGP with which we have done EDI.

I kept the AES items for those folks that can do it.  But, CAST5 is first on
the list for the PGP folks.

Look at the setpref and updpref commands.

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Our organization has a partner who claims that version 7.0.1 of
PGP is incompatible with all versions of GnuPG (as well as PGP
v8.0.2).  Basically, this person has stated that GnuPG defaults
to AES256, AES192, and AES128 symmetric algorithms as the
preferred symmetric algorithms when creating a key, and that
this is the cause of the incompatibility.

Is it possible to create a new GPG key that excludes any and all
AES algorithms.  If so, how would one go about doing such a
thing?

TIA

Adam
