    Panic, Chaos, Ahahahaha!!! :yuck:

    Don't worry though, it is still very difficult to crack unless you have a legion of computers at your bidding. Just start thinking about moving to SHA-256.

    Considering that you must have a large number of powerful systems to do the bidding, this isn't so bad; however, the thought that many, many internet services use SHA-1is quite scary. The most important and common of these services being IPsec, which is responsible for most, if not all, of the VPN networks in the world.

    Yeah, it may not effect us common folks that much, but this is a big deal to government organizations who are now more vulnerable to other countries with the computing power capable of cracking these type of cryptographic systems.

    Shor's algorithm for quantum computing comes to mind (yet again) where breaking a 512 bit RSA key would take a matter of weeks..

    Does such an algorithm already exist??? :bugeye:

    DEC has also been broken. Now should be the turn of RSA, and SSL also!
