Consequently, it bcrypt calls a different + * _encryptBlock() then the regular Blowfish does. That said, the Blowfish _encryptBlock() is + * basically just a thin wrapper around the bcrypt _encryptBlock(), so there's that. + * + * This explains 3 of the 4 _encryptBlock() implementations. the last _encryptBlock() + * implementation can best be understood by doing Ctrl + F and searching for where + * self::$use_reg_intval is defined. + * + * # phpseclib's three different _setupKey() implementations + * + * Every bcrypt round is the equivalent of encrypting 512KB of data. Since OpenSSH uses 16 + * rounds by default that's ~8MB of data that's essentially being encrypted whenever + * you use bcrypt. That's a lot of data, however, bcrypt operates within tighter constraints + * than regular Blowfish, so we can use that to our advantage. In particular, whereas Blowfish + * supports variable length keys, in bcrypt, the initial "key" is the sha512 hash of the + * password. sha512 hashes are 512 bits or 64 bytes long and thus the bcrypt keys are of a + * fixed length whereas Blowfish keys are not of a fixed length. + * + * bcrypt actually has two different key expansion steps. The first one (expandstate) is + * constantly XOR'ing every _encryptBlock() parameter against the salt prior _encryptBlock()'s + * being called. The second one (expand0state) is more similar to Blowfish's _setupKey() + * but it can still use the fixed length key optimization discussed above and can do away with + * the pack() / unpack() calls. + * + * I suppose _setupKey() could be made to be a thin wrapper around expandstate() but idk it's + * just a lot of work for very marginal benefits as _setupKey() is only called once for + * regular Blowfish vs the 128 times it's called --per round-- with bcrypt. + * + * # blowfish + bcrypt in the same class + * + * Altho there's a lot of Blowfish code that bcrypt doesn't re-use, bcrypt does re-use the + * initial S-boxes, the initial P-array and the int-only _encryptBlock() implementation. + * + * # Credit + * + * phpseclib's bcrypt implementation is based losely off of OpenSSH's implementation: + * + * https://github.com/openssh/openssh-portable/blob/master/openbsd-compat/bcrypt_pbkdf.c + * + * Here's a short example of how to use this library: + * + * setKey('12345678901234567890123456789012');

Although an individual modular reduction takes more time + * then an individual division, when performed in succession (with the same modulo), they're a lot faster. + * + * The two most commonly used modular reductions are Barrett and Montgomery reduction. Montgomery reduction, + * although faster, only works when the gcd of the modulo and of the base being used is 1. In RSA, when the + * base is a power of two, the modulo - a product of two primes - is always going to have a gcd of 1 (because + * the product of two odd numbers is odd), but what about when RSA isn't used? + * + * In contrast, Barrett reduction has no such constraint. As such, some bigint implementations perform a + * Barrett reduction after every operation in the modpow function. Others perform Barrett reductions when the + * modulo is even and Montgomery reductions when the modulo is odd. BigInteger.java's modPow method, however, + * uses a trick involving the Chinese Remainder Theorem to factor the even modulo into two numbers - one odd and + * the other, a power of two - and recombine them, later.
