A new Facebook chat encrypter has been released in the form of a Facebook plugin. The Facebook chat encrypter will encrypt your Facebook chat messages with AES encryption. The developer claims that it will add a simple lock icon in your chat box which (once clicked) allow you to setup a password for the encryption of the Facebook messages.
The use of the encryption is very straight forward. First you install the plugin.
Once installed , you can send a message to your friend with encryption enabled, but first you will have to setup a password.
