5.6.8 Mail Encryption

Command: gpg-passphrase passphrase

Specifies your private key’s pass phrase for signing messages using the GNU Privacy Guard. To protect your passwords from being compromised, use the 0600 (u=rw,g=,o=) permissions for the configuration file, otherwise GNU Anubis won’t accept them.

We recommend setting the ‘gpg-passphrase’ once in your configuration file, e.g. at the start of RULE section.

GNU Anubis support for the GNU Privacy Guard is based on the GnuPG Made Easy library, available from http://www.gnupg.org/gpgme.html.

Command: gpg-encrypt gpg-keys

This command enables encrypting messages with the GNU Privacy Guard (Pretty Good Privacy) public key(s). gpg-keys is a comma separated list of keys (with no space between commas and keys).

gpg-encrypt "John's public key"

Command: gpg-sign gpg-signer-key

Command: gpg-sign ‘yes-or-default’

This command signs the message with your GNU Privacy Guard private key. Specify a passphrase with gpg-passphrase. Value ‘default’ means your default private key, but you can change it if you have more than one private key.

For example:

gpg-sign default

or

gpg-passphrase "my office key passphrase"
gpg-sign office@example.key

Command: gpg-sign-encrypt gpg-keys[:gpg-signer-key]

Command: gpg-se gpg-keys[:gpg-signer-key]

This command simultaneously signs and encrypts the message. It has the same effect as gpg command line switch ‘-se’. The argument before the colon is a comma-separated list of PGP keys to encrypt the message with. This argument is mandatory. The gpg-signer-key part is optional. In the absence of it, your default private key is used.

For example:

gpg-sign-encrypt John@example.key

or

gpg-se John@example.key:office@example.key
