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

Features include

• Automatically creates a public/private key pair for you upon loading the plugin
• Automatically transmits your public key to other users.
• Supports 512 - 4096 bit keys.
• Saves keys of known users, and warns you if their public key has changed.
• Embeds all encryption and keys inside HTML, so if the other user doesn't have the plugin, they will get a little message telling them about the plugin, and won't get a screen full of garbage.
• 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 shouldn't have to do.
• Automatically recognizes if you are chatting with someone who has the plugin- see the Preferences dialog.
• Available for the Windows version of Pidgin.
• 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.
