PGP and GnuPG compatibility issue

[dwpalmer at dwpalm.jf.intel.com]

Hopefully going over all these permutations is not needed.  PGP 5.5
doesn't automate all that well.

I've tried MD5, SHA1, and RIPEMD160 with 3DES.  All fail in the same
way, but almost works.  The file that PGP creates has everything but
the first few lines of the original file before complaining, "The
keyring contains a bad (corrupted) PGP packet."  Note that everything
works fine when using much smaller files.

The following is a diff of the two files.  The file "try001" is what
PGP creates.  The original text file is "h:/secrets.txt".

E:/$ diff try001 h:/secrets.txt

Any ideas?
