This kind of IT extortion is profitable for the bad guys as it … |
 | # BlowFish? # BlowFish was the brain child of Bruce Schneier back in 93. Since BlowFish was released to the public domain, Bruce Schneier has released new encryption algorythems, TwoFish and ThreeFish. BlowFish is an increddibly popular and very strong algorythem.
