Hi:

In trying to move a PGP 6.0.2 key pair to GnuPG 1.2.1, I get a variety of
errors with various attempts at decryption of a test file which was also
encrypted with GnuPG.  This is using GPG under Windows 98SE and is part of a
package, but the errors are duplicable calling GPG from the command prompt.

	gpg: onepass_sig with unknown version 201
	gpg: [don't know]: invalid packet (ctb=43)
	gpg: mpi too large (56839 bits)

Any information on options or procedures that should be used when importing
an old PGP key would be appreciated.  Some detail follows.

--list-secret-keys  --verbose
	sec  1024D/E7F90291 2004-05-04 abc <abc>
	ssb  2048g/CF8E4F56 2004-05-04

--list-keys --verbose
	pub  1024D/E7F90291 2004-05-04 abc <abc>
	sig         E7F90291 2004-05-04   abc <abc>
	sub  2048g/CF8E4F56 2004-05-04
	sig         E7F90291 2004-05-04   abc <abc>

The encryption generates:
gpg: using secondary key CF8E4F56 instead of primary key E7F90291
gpg: using secondary key CF8E4F56 instead of primary key E7F90291
gpg: abc: skipped: public key already present
gpg: using secondary key CF8E4F56 instead of primary key E7F90291
gpg: No trust check due to --always-trust option
gpg: abc: skipped: public key already present
gpg: reading from `C:\xxx\SYSTESTD.TXT'
gpg: writing to `C:\xxx\SYSTES~1.PGP'
gpg: ELG-E/CAST5 encrypted for: "CF8E4F56 abc <abc>"

Best Regards,
