Development: Crypto

The test keys used for testing the crypto suite expires after one year, to regenerate:

0. Set the GNUPGHOME environment variable to: /full/path/test/gnupg_test_home/
1. Generate receiver keys for email: sup-test-2@foo.bar (no password)
2. Export key
3. Move keyrings to receiver_*.gpg
4. Generate sender keys for email: sup-test-1@foo.bar (no password)
5. Import receiver key and 'trust' it (trust probably not needed because of trust-model in gpg.conf).

or check the script regen_keys.sh in test/gnupg_test_home/.
