This is THE method when communicating over a totally open channel like the internet. The message is encrypted on your computer and decrypted on the receivers computer. A drawback is that you have to "handshake" with each of the receivers first. New keys are generated on the fly (off the record) such that if your secret key is compromised no old messages can be decrypted still. Wikipedia has a small article about it and it works quite easily once set up in kopete. Best Thomas >=20 > Best regards, >=20 > Wen >=20 --=20 Thomas Kahle The fundamental theorem of algebra is open source. Like any other mathematical theorem it can be applied free of charge and everybody has access to its proof and can convince himself how it works. Why should software be any different? --------------enig404075A024671DC722489494 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkqJVncACgkQrpEWPKIUt7OoKACfdUqajD77Jgacr63nroBUv0dQ /60Anj0GCHB075xt6LYVU5GZEU7wpc7I =bYBS -----END PGP SIGNATURE----- --------------enig404075A024671DC722489494--
