You're joking, right?
a) Even a DES key would take you YEARS to break by experimentation.
b) 3DES is considered unbreakable for practical purposes
c) The AES algorithm is considered by the NSA to be acceptable for the encryption of data classified as Top Secret, when it's used with either a 192 bit or a 256 bit key. This means it is sufficiently close to impossible to break with existing technology as to be considered "unbreakable".
Motorola radios (the only ones I know about) can be configured to use DES, 3DES, or AES with key sizes up to 256 bits.
So, just let me get this right: You, sitting at home with a couple of radios, seriously believe that you've discovered a way to break an encryption alogrithm that the NSA has declared safe for TOP SECRET information?
Forgein governments have rooms full of super-computers and mathematicians and they're not able to break AES 256 encryption. But you can?
C'mon... Does that make sense to you?

You've hit on a significant point here. Key length is a very important variable. If you use a very short key, even the most complex encryption algorithms are vulnerable. No one with any knowledge about these things uses a very short key. If I recall correctly, for each additional bit of key length, the solution becomes twice as difficult. Even with a lot of spare time, a 256 bit key is beyond the ability to solve by trial and error (brute force). Some day they may have computers fast and powerful enough to solve 256 bit AES encryption. Then they will use 512 bit encryption and it's again beyond the ability to break.
