How well meant your advice is, and a happy new year to you, it doesnt give
you status 4 in encryption, meaning top secret government level. It takes a
mere 15-20 minutes to crack any single 128 bits engine so I think you have
either NO knowledge about encryption and or forensic research. Verisign for
instance is one of the least safest way to encrypt: the man in the middle is
always possible, how hard they try to prevent it.

Believe me, we have an engine that will take you 1 over 10^1256 attempts to
crack: good luck.
128 bits is cracked in no time at all.

That's odd. I've spent half my professional life as the CTO of an major publicly traded encryption company and somehow I had never noticed that all the published cryptographic research in the world is wrong and you're right...

To date the largest symmetric encryption key publicly broken by brute force is a 64 bit RC5 key. It took a distributed effort of thousands of computers most of a year to do so. Breaking a 128 bit key is 2^64 time, or about 18.4 million million million times harder. While conspiracy theorists might think that this is breakable by the spooks the vast majority of opinion is that this is sufficient for most applications.
