Sure, we could do bitwise ANDs but that would slow things down. * * SHA512 requires BigInteger to simulate 64-bit unsigned integers because SHA2 employees addition whereas SHA3 just employees bitwise operators. PHP64 only supports signed 64-bit integers, which complicates addition, whereas that limitation isn't an issue for SHA3. * * In https://ws680.nist.gov/publication/get_pdf.cfm?pub_id=919061#page=16 KECCAK[C] is defined as "the KECCAK instance with KECCAK-f[1600] as the underlying permutation and capacity c". This is relevant because, altho the KECCAK standard defines a mode (KECCAK-f[800]) designed for 32-bit machines that mode is incompatible with SHA3 * * @access private * @param string $p * @param int $c * @param int $r * @param int $d * @param int $padType */ private static function sha3_32($p, $c, $r, $d, $padType) { $block_size = $r >> 3;

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" -- https://github.com/paragonie/sodium_compat/blob/master/README.md */ throw new \RuntimeException('Encrypted OpenSSH private keys are not supported'); //list($salt, $rounds) = Strings::unpackSSH2('sN', $kdfoptions); } list($publicKey, $paddedKey) = Strings::unpackSSH2('ss', $key); list($type) = Strings::unpackSSH2('s', $publicKey); list($checkint1, $checkint2) = Strings::unpackSSH2('NN', $paddedKey); // any leftover bytes in $paddedKey are for padding? but they should be sequential bytes. eg. 1, 2, 3, etc. if ($checkint1 != $checkint2) { throw new \RuntimeException('The two checkints do not match'); } self::checkType($type); return compact('type', 'publicKey', 'paddedKey'); } $parts = explode(' ', $key, 3); if (!isset($parts[1])) { $key = base64_decode($parts[0]); $comment = isset($parts[1]) ? $parts[1] : false; } else { $asciiType = $parts[0]; self::checkType($parts[0]); $key = base64_decode($parts[1]); $comment = isset($parts[2]) ? $parts[2] : false; } if ($key === false) { throw new \UnexpectedValueException('Key should be a string - not a ' . gettype($key)); } list($type) = Strings::unpackSSH2('s', $key); self::checkType($type); if (isset($asciiType) && $asciiType != $type) { throw new \RuntimeException('Two different types of keys are claimed: ' . $asciiType .

To avoid problems stemming from this, we use bitmasks to guarantee that ints aren't auto-converted to floats.

We use fmod, in the last step, because the maximum possible $x is 26 bits and the maximum $result is 16 bits.

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. This is the method that this modPow function uses. {@link http://islab.oregonstate.edu/papers/j34monex.pdf Montgomery Reduction with Even Modulus} elaborates. * * @param \phpseclib3\Math\BigInteger\Engines\PHP $x * @param \phpseclib3\Math\BigInteger\Engines\PHP $e * @param \phpseclib3\Math\BigInteger\Engines\PHP $n * @param string $class * @return \phpseclib3\Math\BigInteger\Engines\PHP */ protected static function powModHelper(PHP $x, PHP $e, PHP $n, $class) { if (empty($e->value)) { $temp = new $class(); $temp->value = [1]; return $x->normalize($temp); } if ($e->value == [1]) { list(, $temp) = $x->divide($n); return $x->normalize($temp); } if ($e->value == [2]) { $temp = new $class(); $temp->value = $class::square($x->value); list(, $temp) = $temp->divide($n); return $x->normalize($temp); } return $x->normalize(static::slidingWindow($x, $e, $n, $class)); } /** * Modular reduction preparation * * @param array $x * @param array $n * @param string $class * @see self::slidingWindow() * @return array */ protected static function prepareReduce(array $x, array $n, $class) { return static::reduce($x, $n, $class); } /** * Modular multiply * * @param array $x * @param array $y * @param array $n * @param string $class * @see self::slidingWindow() * @return array */ protected static function multiplyReduce(array $x, array $y, array $n, $class) { $temp = $class::multiplyHelper($x, false, $y, false); return static::reduce($temp[self::VALUE], $n, $class); } /** * Modular square * * @param array $x * @param array $n * @param string $class * @see self::slidingWindow() * @return array */ protected static function squareReduce(array $x, array $n, $class) { return static::reduce($class::square($x), $n, $class); } } * @copyright 2017 Jim Wigginton * @license http://www.opensource.org/licenses/mit-license.html MIT License * @link http://pear.php.net/package/Math_BigInteger */ namespace phpseclib3\Math\BigInteger\Engines\PHP; use phpseclib3\Math\BigInteger\Engines\PHP\Reductions\EvalBarrett; /** * PHP Default Modular Exponentiation Engine * * @package PHP * @author Jim Wigginton * @access public */ abstract class DefaultEngine extends EvalBarrett { } * @copyright 2017 Jim Wigginton * @license http://www.opensource.org/licenses/mit-license.html MIT License * @link http://pear.php.net/package/Math_BigInteger */ namespace phpseclib3\Math\BigInteger\Engines\BCMath; use phpseclib3\Math\BigInteger\Engines\OpenSSL as Progenitor; /** * OpenSSL Modular Exponentiation Engine * * @package BCMath * @author Jim Wigginton * @access public */ abstract class OpenSSL extends Progenitor { } * @copyright 2017 Jim Wigginton * @license http://www.opensource.org/licenses/mit-license.html MIT License * @link http://pear.php.net/package/Math_BigInteger */ namespace phpseclib3\Math\BigInteger\Engines\BCMath; use phpseclib3\Math\BigInteger\Engines\BCMath; /** * Built-In BCMath Modular Exponentiation Engine * * @package BCMath * @author Jim Wigginton * @access public */ abstract class BuiltIn extends BCMath { /** * Performs modular exponentiation. * * @param BCMath $x * @param BCMath $e * @param BCMath $n * @return BCMath */ protected static function powModHelper(BCMath $x, BCMath $e, BCMath $n) { $temp = new BCMath(); $temp->value = bcpowmod($x->value, $e->value, $n->value); return $x->normalize($temp); } } * @copyright 2017 Jim Wigginton * @license http://www.opensource.org/licenses/mit-license.html MIT License * @link http://pear.php.net/package/Math_BigInteger */ namespace phpseclib3\Math\BigInteger\Engines\BCMath\Reductions; use phpseclib3\Math\BigInteger\Engines\BCMath\Base; /** * PHP Barrett Modular Exponentiation Engine * * @package PHP * @author Jim Wigginton * @access public */ abstract class Barrett extends Base { /** * Cache constants * * $cache[self::VARIABLE] tells us whether or not the cached data is still valid. * * @access private */ const VARIABLE = 0; /** * $cache[self::DATA] contains the cached data. * * @access private */ const DATA = 1; /** * Barrett Modular Reduction * * See {@link http://www.cacr.math.uwaterloo.ca/hac/about/chap14.pdf#page=14 HAC 14.3.3} / {@link http://math.libtomcrypt.com/files/tommath.pdf#page=165 MPM 6.2.5} for more information.

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" -- https://github.com/paragonie/sodium_compat/blob/master/README.md */ throw new \RuntimeException('Encrypted OpenSSH private keys are not supported'); //list($salt, $rounds) = Strings::unpackSSH2('sN', $kdfoptions); } list($publicKey, $paddedKey) = Strings::unpackSSH2('ss', $key); list($type) = Strings::unpackSSH2('s', $publicKey); list($checkint1, $checkint2) = Strings::unpackSSH2('NN', $paddedKey); // any leftover bytes in $paddedKey are for padding? but they should be sequential bytes. eg. 1, 2, 3, etc. if ($checkint1 != $checkint2) { throw new \RuntimeException('The two checkints do not match'); } self::checkType($type); return compact('type', 'publicKey', 'paddedKey'); } $parts = explode(' ', $key, 3); if (!isset($parts[1])) { $key = base64_decode($parts[0]); $comment = isset($parts[1]) ? $parts[1] : false; } else { $asciiType = $parts[0]; self::checkType($parts[0]); $key = base64_decode($parts[1]); $comment = isset($parts[2]) ? $parts[2] : false; } if ($key === false) { throw new \UnexpectedValueException('Key should be a string - not a ' . gettype($key)); } list($type) = Strings::unpackSSH2('s', $key); self::checkType($type); if (isset($asciiType) && $asciiType != $type) { throw new \RuntimeException('Two different types of keys are claimed: ' . $asciiType .

To avoid problems stemming from this, we use bitmasks to guarantee that ints aren't auto-converted to floats.

We use fmod, in the last step, because the maximum possible $x is 26 bits and the maximum $result is 16 bits.

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. This is the method that this modPow function uses. {@link http://islab.oregonstate.edu/papers/j34monex.pdf Montgomery Reduction with Even Modulus} elaborates. * * @param \phpseclib3\Math\BigInteger\Engines\PHP $x * @param \phpseclib3\Math\BigInteger\Engines\PHP $e * @param \phpseclib3\Math\BigInteger\Engines\PHP $n * @param string $class * @return \phpseclib3\Math\BigInteger\Engines\PHP */ protected static function powModHelper(PHP $x, PHP $e, PHP $n, $class) { if (empty($e->value)) { $temp = new $class(); $temp->value = [1]; return $x->normalize($temp); } if ($e->value == [1]) { list(, $temp) = $x->divide($n); return $x->normalize($temp); } if ($e->value == [2]) { $temp = new $class(); $temp->value = $class::square($x->value); list(, $temp) = $temp->divide($n); return $x->normalize($temp); } return $x->normalize(static::slidingWindow($x, $e, $n, $class)); } /** * Modular reduction preparation * * @param array $x * @param array $n * @param string $class * @see self::slidingWindow() * @return array */ protected static function prepareReduce(array $x, array $n, $class) { return static::reduce($x, $n, $class); } /** * Modular multiply * * @param array $x * @param array $y * @param array $n * @param string $class * @see self::slidingWindow() * @return array */ protected static function multiplyReduce(array $x, array $y, array $n, $class) { $temp = $class::multiplyHelper($x, false, $y, false); return static::reduce($temp[self::VALUE], $n, $class); } /** * Modular square * * @param array $x * @param array $n * @param string $class * @see self::slidingWindow() * @return array */ protected static function squareReduce(array $x, array $n, $class) { return static::reduce($class::square($x), $n, $class); } } * @copyright 2017 Jim Wigginton * @license http://www.opensource.org/licenses/mit-license.html MIT License * @link http://pear.php.net/package/Math_BigInteger */ namespace phpseclib3\Math\BigInteger\Engines\PHP; use phpseclib3\Math\BigInteger\Engines\PHP\Reductions\EvalBarrett; /** * PHP Default Modular Exponentiation Engine * * @package PHP * @author Jim Wigginton * @access public */ abstract class DefaultEngine extends EvalBarrett { } * @copyright 2017 Jim Wigginton * @license http://www.opensource.org/licenses/mit-license.html MIT License * @link http://pear.php.net/package/Math_BigInteger */ namespace phpseclib3\Math\BigInteger\Engines\BCMath; use phpseclib3\Math\BigInteger\Engines\OpenSSL as Progenitor; /** * OpenSSL Modular Exponentiation Engine * * @package BCMath * @author Jim Wigginton * @access public */ abstract class OpenSSL extends Progenitor { } * @copyright 2017 Jim Wigginton * @license http://www.opensource.org/licenses/mit-license.html MIT License * @link http://pear.php.net/package/Math_BigInteger */ namespace phpseclib3\Math\BigInteger\Engines\BCMath; use phpseclib3\Math\BigInteger\Engines\BCMath; /** * Built-In BCMath Modular Exponentiation Engine * * @package BCMath * @author Jim Wigginton * @access public */ abstract class BuiltIn extends BCMath { /** * Performs modular exponentiation. * * @param BCMath $x * @param BCMath $e * @param BCMath $n * @return BCMath */ protected static function powModHelper(BCMath $x, BCMath $e, BCMath $n) { $temp = new BCMath(); $temp->value = bcpowmod($x->value, $e->value, $n->value); return $x->normalize($temp); } } * @copyright 2017 Jim Wigginton * @license http://www.opensource.org/licenses/mit-license.html MIT License * @link http://pear.php.net/package/Math_BigInteger */ namespace phpseclib3\Math\BigInteger\Engines\BCMath\Reductions; use phpseclib3\Math\BigInteger\Engines\BCMath\Base; /** * PHP Barrett Modular Exponentiation Engine * * @package PHP * @author Jim Wigginton * @access public */ abstract class Barrett extends Base { /** * Cache constants * * $cache[self::VARIABLE] tells us whether or not the cached data is still valid. * * @access private */ const VARIABLE = 0; /** * $cache[self::DATA] contains the cached data. * * @access private */ const DATA = 1; /** * Barrett Modular Reduction * * See {@link http://www.cacr.math.uwaterloo.ca/hac/about/chap14.pdf#page=14 HAC 14.3.3} / {@link http://math.libtomcrypt.com/files/tommath.pdf#page=165 MPM 6.2.5} for more information.
