File encryption. This application uses the serpent multiblock encryption algorithm with 'bit-slicing' technique 128 bits block size. Supports 128-, 192- and 256-bit length key sizes. Serpent is a strong public algorithm, created with a century estimated time of life. This Serpent implementation is indicated for maximum security precise tasks with small archives, because the very slow process speed. This version is the first release on CNET Download.com.
