Topal is yet another program that links GnuPG and Pine/Alpine. It offers facilities to encrypt, decrypt, sign, and verify messages. Multiple PGP blocks included in the text of a message are processed. Decryption and verification output can be cached to reduce the number of times the passphrase is entered. RFC2015/3156 multipart messages can be sent and received with help from some scripts, procmail, and a patch to Pine/Alpine. There is a high level of configurability. License: GNU General Public License v3Changes:
The fix-email workaround was updated. Some key selection code was replaced to reduce the number of locale-dependent and GPG version-specific problems. Revoked, disabled, and invalid keys are no longer offered. Checks are made to ensure that the key is valid for encryption/signing when applicable. A new patch was provided for Alpine 1.00. Cygwin should now work. The licence is now GPL 3. Further minor changes were made, including the prevention of memory leaks, cleaning of warnings, better checks on keylists, and documentation clean-ups.
