TwofishCFB1 Class (console safe)
Twofish is a block cipher, it was one of the five Advanced Encryption Standard (AES) finalists. The Twofish algorithm has been extensively crypto-analyzed.
When Twofish is in CFB1 mode then the blocks are chained together with a IV vector.
The key size in Twofish can be 128,192 or 256 bits.
The block size in Twofish is 128 bits (16 bytes).

Methods
Decrypt | Use this function to decrypt a block of data.
Because Twofish works on blocks of 16 bytes then you get the best performance if the block size that you pass to it is dividable by 16. The class has built in cache technology so it will work if the the block size is not dividable by 16, but it will be slower. |
Encrypt | Use this function to encrypt a block of data.
Because Twofish works on blocks of 16 bytes then you get the best performance if the block size that you pass to it is dividable by 16. The class has built in cache technology so it will work if the the block size is not dividable by 8, but it will be slower. |
FinishDecrypt | Use this function to finish decrypting after you have decrypted all of the blocks. |
FinishEncrypt | Use this function to finish encrypting after you have encrypted all of the blocks. |
PaddingBlockSize | Use this property to get the padding value that is needed for this algorithm. (Twofish will always return 16 here). |
Constants
KeyTypeEncrypt = 0 | A constant that specifies that a Key is for encryption |
KeyTypeDecrypt = 1 | A constant that specifies that a Key is for decryption |
KeyTypeBoth = 2 | A constant that specifies that a Key is for either encryption or decryption |
