Constructor & Destructor Documentation

◆ twofish_crypto() [1/3]

crypto::twofish_crypto::twofish_crypto ( int key_size )

this will create a new random key of the "key_size", in bits.

the valid sizes are from 128 bits to 256 bits. AES apparently only requires that 128, 192 and 256 actually work, but the intervening key sizes should be fine also.
