Pidgin-Encryption (formerly Gaim-Encryption) 3.0

Pidgin-Encryption (formerly Gaim-Encryption) 3.0  offers you a useful pidgin plugin  to provide transparent RSA encryption.

Pidgin-Encryption transparently encrypts your instant messages with RSA encryption. Easy-to-use, but very secure.

Major Features:

1. Automatically creates a public/private key pair for you upon loading the plugin
2. Automatically transmits your public key to other users.
3. Supports 512 4096 bit keys.
4. Saves keys of known users, and warns you if their public key has changed.
5. Embeds all encryption and keys inside HTML, so if the other user doesnt have the plugin, they will get a little message telling them about the plugin, and wont get a screen full of garbage.
6. Stores keys in human readable files in your .gaim/.pidgin directory, in case you ever need to copy/edit them by hand. Which you really shouldnt have to do.
7. Automatically recognizes if you are chatting with someone who has the pluginsee the Preferences dialog.
8. Available for the Windows version of Pidgin.
9. Modular and extensible. If you want to define a different type of encryption, you can use this plugin as a wrapper to take care of transporting the encrypted binary over the IM pipe.
