This is my first message on the list and it immediately is a request for help ;-)

I used to use PGP with Pegasus Mail but switched my email system to Thunderbird + GnuPG + Enigmail. I often receive encrypted emails, from a variety of people. I have noticed that I regularly have the following problem:

When trying to decrypt a message that comes from someone with PGP 9, I get the following error:

gpg.exe --charset utf8 --batch --no-tty --status-fd 2 -d -- passphrase-fd 0 --no-use-agent ,gpg: invalid radix64 character 3A skipped,gpg: invalid radix64 character 2E skipped,gpg: invalid radix64 character 2E skipped,gpg: invalid radix64 character 28 skipped,gpg: invalid radix64 character 29 skipped,gpg: invalid radix64 character 3A skipped,gpg: invalid radix64 character 2D skipped,gpg: CRC error; 188EB4 - 9C15D0,gpg: [don't know]: invalid packet (ctb=55)

PGP has no problems decrypting these messages. When I remove the comment lines inserted by PGP (e.g. Version: PGP Desktop 9.8.3 (Build 4028), GnuPG can also decrypt the messages without any problems.

My question is if there is a work around for this, or if there is an option that can be used so that the comment line does not interfere with the decryption.

This come up now and then. The problem, as you noted, is the comment line. Basically, the PGP comment line is long enough that many mailers word-wrap it. Thus, the message that gets passed to GPG is something like:

 -----BEGIN PGP MESSAGE-----
 Version: PGP 8.0.2 - not licensed for commercial use:
 www.pgp.com

 qANQR1DBw04Dxrpn2akpjMkQD/457fxRygbnZG7jAssMb4JuMeXqZdXmMhcGetrm
 ...
 -----END PGP MESSAGE-----

Note the "www.pgp.com" wrapped to the next line. There isn't much you can do about it except check the various word-wrap settings involved. Some mailers are 'helpful' and break the line in two.
