* # An overview of bcrypt vs Blowfish
|
||||
*
|
||||
* OpenSSH private keys use a customized version of bcrypt. Specifically, instead of
|
||||
* encrypting OrpheanBeholderScryDoubt 64 times OpenSSH's bcrypt variant encrypts
|
||||
* OxychromaticBlowfishSwatDynamite 64 times. so we can't use crypt().
|
||||
*
|
||||
* bcrypt is basically Blowfish but instead of performing the key expansion once it performs
|
||||
* the expansion 129 times for each round, with the first key expansion interleaving the salt
|
||||
* and password. 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_SAFE_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.

OpenSSH private keys use a customized version of bcrypt. specifically, instead of encrypting
|
||||
OrpheanBeholderScryDoubt 64 times OpenSSH's bcrypt variant encrypts
|
||||
OxychromaticBlowfishSwatDynamite 64 times. so we can't use crypt().
|
||||
|
||||
bcrypt is basically Blowfish with an altered key expansion. whereas Blowfish just runs the
|
||||
key through the key expansion bcrypt interleaves the key expansion with the salt and
|
||||
password. this renders openssl / mcrypt unusuable. this forces us to use a pure-PHP implementation
|
||||
of bcrypt. the problem with that is that pure-PHP is too slow to be practically useful.
|
||||
|
||||
in addition to encrypting a different string 64 times the OpenSSH implementation also performs bcrypt
|
||||
from scratch $rounds times. calling crypt() 64x with bcrypt takes 0.7s. PHP is going to be naturally
|
||||
slower. pure-PHP is 215x slower than OpenSSL for AES and pure-PHP is 43x slower for bcrypt.
|
||||
43 * 0.7 = 30s. no one wants to wait 30s to load a private key.
|
||||
|
||||
another way to think about this.. according to wikipedia's article on Blowfish,
|
||||
"Each new key requires pre-processing equivalent to encrypting about 4 kilobytes of text".
|
||||
key expansion is done (9+64*2)*160 times. multiply that by 4 and it turns out that Blowfish,
|
||||
OpenSSH style, is the equivalent of encrypting ~80mb of text.
|
||||
|
||||
more supporting evidence: sodium_compat does not implement Argon2 (another password hashing
|
||||
algorithm) because "It's not feasible to polyfill scrypt or Argon2 into PHP and get reasonable
|
||||
performance. Users would feel motivated to select parameters that downgrade security to avoid
|
||||
denial of service (DoS) attacks. The only winning move is not to play"
