Crypto Speak is a free program that allows two users to talk and communicate with each other through the computer's microphone and speakers completely safely. For this, it uses a TCP / IP connection with very high levels of encryption. Everything is done automatically in the background, without the need for user intervention.
There are many programs that allow communication or instant messaging through voice, but very few offer such strong and reliable encryption as Crypto Speak.
This program allows us to establish encrypted connections to communicate with our contacts, and also its source code is available for us to see and modify if we consider it necessary. You will not find vulnerabilities or security holes.
You can free download Crypto Speak 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
