* Uses the groups module to prepare a list of recipients and encrypt to those. * The main version (encrypt-to-group.py) tries to check for invalid recipients, but still falls back to always trust for the second encryption attempt. * The gullible version doesn't try pruning the recipient list at all, it just tries to encrypt and if it fails, switches straight to always trust. * The trustno1 version doesn't use the always trust model at all and only attempts pruning the list of invalid recipients.
