These days the whole world uses instant messaging programs to have conversations with their contacts; many of these conversations are trivial, but some could be very important, private and confidential.
To maintain your confidentiality in these conversations, IMCrypto Freehas been created. It is a program that encrypts and protects everything written via these instant messaging programs (it works with Windows Live Messenger, Yahoo Messenger, ICQ, etc).
This version of IMCrypto is totally free, but it has the limitation of only being used by one client. On the author`s website there is a professional version, which is shareware, but much more complete and for all messaging programs.
