Blowsearch Secured Messenger utilizes the OpenSSL library to provide encryption routines for your Instant Messages. We use a combination of randomly selected schemes and bit lengths, ranging up to 4096 bits, with additional algorithms added in to make your messages even more secure. We start with an RSA foundation and move out from there.

Your Random RSA Public Key is transferred to a server which uses a public key to transfer it. That public key is then sent to anyone who sends you an IM. It is important to note that you always transfer encrypted data using your buddy's public key and key strength and they always send to you using your public key and key strength. Private keys are then used by the client to decrypt incoming messages encoded using the public key.

If the instant message recipient does not have the Blowsearch Secured Messenger enabled or installed on their computer then nothing is encrypted and your communications will carry on as usual.   All of this is seamless to the user.  The only way you would know that a message is secured, is the addition of BSM lock logos, which will appear in your chat window.
