A method that increases the security of a message or a file by encoding the content, so that it can only be read by the person who has the appropriate encryption key to decode it. Blowfish implementations use 16 rounds of encryption, and are not susceptible to this attack. This constraint is not a problem even for older desktop and laptop computers, though it does prevent use in the smallest embedded systems such as early smartcards. 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). This is not so obvious because xor is commutative and associative.
