I was searching for an istant messaging client that offers an encryption system. This will be a guarantee to future customers of my site when I'll talk with us. During my research I have found this program called X-IM, they promise an "industrial" level of messages encryption. I haven't eard its name, so I ask if someone know it and know if it is really safety.
They told that if a customer want to test its safety, they will provide him/her the source code of the software. But I can't "read" the source code of a sotware and this will not help me.
