gnupg 6.x-1.0-alpha1

The first alpha release for Drupal 6.x, supporting public-key encryption using GnuPG. Decryption has not yet been implemented.

Features:

• Provides configuration for the locations of the gpg command-line binary and the GnuPG home directory.
• Provides system status report entries indicating whether GnuPG is installed correctly.
• Adds a new cryptography tab when editing user accounts, allowing users to paste in and store their public keys (for later use by this module or other modules).
• Exports a maximally simple API consisting of the gnupg_version(), gnupg_encrypt() and gnupg_decrypt() functions (but note that decryption is not implemented yet in this release).
• Includes comprehensive API documentation.
• Implements some basic Simpletest 2.x-compatible unit tests.
