This renders OpenSSL unusable and forces us to use a pure-PHP implementation + * of blowfish. + * + * # phpseclib's four different _encryptBlock() implementations + * + * When using Blowfish as an encryption algorithm, _encryptBlock() is called 9 + 512 + + * (the number of blocks in the plaintext) times. + * + * Each of the first 9 calls to _encryptBlock() modify the P-array. Each of the next 512 + * calls modify the S-boxes. The remaining _encryptBlock() calls operate on the plaintext to + * produce the ciphertext. In the pure-PHP implementation of Blowfish these remaining + * _encryptBlock() calls are highly optimized through the use of eval(). Among other things, + * P-array lookups are eliminated by hard-coding the key-dependent P-array values, and thus we + * have explained 2 of the 4 different _encryptBlock() implementations. + * + * With bcrypt things are a bit different. _encryptBlock() is called 1,079,296 times, + * assuming 16 rounds (which is what OpenSSH's bcrypt defaults to). The eval()-optimized + * _encryptBlock() isn't as beneficial because the P-array values are not constant. Well, they + * are constant, but only for, at most, 777 _encryptBlock() calls, which is equivalent to ~6KB + * of data. The average length of back to back _encryptBlock() calls with a fixed P-array is + * 514.12, which is ~4KB of data. Creating an eval()-optimized _encryptBlock() has an upfront + * cost, which is CPU dependent and is probably not going to be worth it for just ~4KB of + * data. Conseqeuently, bcrypt does not benefit from the eval()-optimized _encryptBlock(). + * + * The regular _encryptBlock() does unpack() and pack() on every call, as well, and that can + * begin to add up after one million function calls. + * + * In theory, one might think that it might be beneficial to rewrite all block ciphers so + * that, instead of passing strings to _encryptBlock(), you convert the string to an array of + * integers and then pass successive subarrays of that array to _encryptBlock. This, however, + * kills PHP's memory use. Like let's say you have a 1MB long string. After doing + * $in = str_repeat('a', 1024 * 1024); PHP's memory utilization jumps up by ~1MB. After doing + * $blocks = str_split($in, 4); it jumps up by an additional ~16MB. After + * $blocks = array_map(fn($x) => unpack('N*', $x), $blocks); it jumps up by an additional + * ~90MB, yielding a 106x increase in memory usage. 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 + * CRYPT_BASE_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: * <code> * <?php @@ -75,6 +156,15 @@ class Blowfish extends Base var $cfb_init_len = 500;
