BlowfishECB Class (console safe)

Blowfish is a symmetric block cipher which takes a variable-length key, from 32 bits to 448 bits. Blowfish has been analysed considerably, and has gained acceptance as a strong encryption algorithm.

When Blowfish is in ECB mode then no block chaining is done.

The block size in Blowfish is 64 bits (8 bytes).

This algorithm has been tested against official test vectors.

Methods

Decrypt (console safe) Use this function to decrypt a block of data. Because Blowfish works on blocks of 8 bytes then you get the best performance if the block size that you pass to it is dividable by 8. 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.
Encrypt (console safe) Use this function to encrypt a block of data. Because Blowfish works on blocks of 8 bytes then you get the best performance if the block size that you pass to it is dividable by 8. 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 (console safe) Use this function to finish decrypting after you have decrypted all of the blocks.
FinishEncrypt (console safe) Use this function to finish encrypting after you have encrypted all of the blocks.
PaddingBlockSize (console safe) Use this property to get the padding value that is needed for this algorithm. (Blowfish will always return 8 here). The Blowfish encrypts in pairs of 8 bytes, so if you have data that does not add up to 8 then you will need to add PaddingBlockSize-1 bytes of random data to ensure that all of your data is encrypted.
Reset (console safe) Use this method to reset the class back to the same parameters as when it was constructed. This method can be used when you want to encrypt/decrypt again without needing to construct the class again. You may not encrypt/decrypt again without constructing a new instance or using the Reset method in between.
