The help file says, it's the standard blowfish algorithm by Bruce Schneier. The methods provided by the library accept also a string password instead of a key, which is internally converted to a key with a chosen Hash function. The key is divided up into 32-bit blocks and XORed with the initial elements of the P and S arrays. Unless there is a flaw in the algorithm and that you know it, your only option is to brute force it which might takes hundred of years. Another opinion is that the 448bits limit is present to ensure that every bit of every subkey depends on every bit of the key,[4] as the last four values of the P-array don't affect every bit of the ciphertext. Depends on what you are wanting to hide ;). There are five subkey-arrays: one 18-entry P-array (denoted as K in the diagram, to avoid confusion with the Plaintext) and four 256-entry S-boxes (S0, S1, S2 and S3). Not the answer you're looking for? The maximal size of the the text string input is 131,072 characters. Why hasn't the Attorney General investigated Justice Thomas? This point should be taken in consideration for implementations with a different number of rounds, as even though it increases security against an exhaustive attack, it weakens the security guaranteed by the algorithm. .
