CommuniCrypt is a new tool for high-secured real-time communication via LAN and Internet. It works like a messenger or a chat tool, but the complete data transfer between both machines are highly encrypted through Public-Key-Encryption with strong asymmetric RSA encryption algorithm (RSAES-OAEP). The key length of public and private key may between 338 and 7120 bit (only in Professional Edition, in Standard Edition fixed to 1024 bit). With CommuniCrypt nobody can read your communication - except you and your chat buddy. It supports now hostname resolving - optimal for DynDNS machines.

Encryption procedure: Public-Key

Encryption algorithm: RSA (RSAES-OEAP)

Key length from 338 bit up to 7120 bit free selectable

no central server needed (like at the most other messengers), the encrypted communication transfering data directly between the participated hosts

based on TCP

uses Port 1555 (incoming)

tested under Windows 2000 SP4 and Windows XP SP2, but should run on all Windows system from Windows 98 up
