Algo : WoltLab BB3

[atom]

@atom: and how is WoltLab BB3 scheme exceeding this limit? Both the hash and the salt are 20 bytes in length (they are in hex). The maximum input length at a time is 40 bytes.

I did not know that it is using a hex encoded digest nor did I know its using a hex encoded salt string. In this case it would use 40 + 40 = 80 which is greater than 55.
