ISequre is a security software application that enables you and your friends or co-workers to exchange ICQ messages securely. ICQ is one of the most popular instant messengers today. Unfortunately, it stores and transmits all messages in non-encrypted form. ISequre will protect your chat session encoding all messages with the Blowfish encryption algorithm. ISequre works transparently and does not add any new interface elements except its icon on the systray. You can use different keys for each of your chat partners simultaneously.
