Adding more privacy to users of existing messengers (yahoo only at this stage)

SQLProxy is a program created for adding more privacy to users of existing messengers (First Yahoo Messenger and later MSN, ICQ…). In first versions, only yahoo messenger protocol is supported.
Updates will be found at

How it works

SQLProxy will run on your computer and on the computer of a friend. Acting as an http proxy it will intercept the messages before they are sent on the network and will encrypt them. At the destination SQLProxy will decrypt them. SQLProxy is acting as a HTTP proxy but knows just enough yahoo messenger protocol to be able to encrypt/decrypt the content of the message.

The transfer of files is not encrypted in any other way. You need only to set a secret key with your friend (by phone or mail, not by messenger) Encryption is done with DES provided by <A HREF=>Crypt++ library

I have plans to add RSA (and key exchange protocol). Crypt++ library is not provided here. Please give me feedbacks if is working for you (or not) at
