+ Requires PHP5, uses built-in DOM extension.
+ To be used in PHP4 scripts using DOMXML extension: allows PHP4/DOMXML scripts to run on PHP5/DOM.
+ (Optional: requires PHP5/XSL extension for domxml_xslt functions, PHP>=5.1 for XPath evaluation functions, and PHP>=5.1/libxml for DOMXML error reports)
+
+ Typical use:
+ {
+ if (PHP_VERSION>='5')
+ require_once('domxml-php4-to-php5.php');

+/**
+ * Pure-PHP implementation of AES.
+ *
+ * Uses mcrypt, if available, and an internal implementation, otherwise.
+ *
+ * PHP versions 4 and 5
+ *
+ * If {@link Crypt_AES::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
+ * {@link Crypt_AES::setKey() setKey()}. ie. if the key is 128-bits, the key length will be 128-bits. If it's 136-bits
+ * it'll be null-padded to 160-bits and 160 bits will be the key length until {@link Crypt_Rijndael::setKey() setKey()}
+ * is called, again, at which point, it'll be recalculated.
+ *
+ * Since Crypt_AES extends Crypt_Rijndael, some functions are available to be called that, in the context of AES, don't
+ * make a whole lot of sense. {@link Crypt_AES::setBlockLength() setBlockLength()}, for instance. Calling that function,
+ * however possible, won't do anything (AES has a fixed block length whereas Rijndael has a variable one).
+ *
+ * Here's a short example of how to use this library:
+ * <code>
+ * <?php
+ * include('Crypt/AES.php');
+ *
+ * $aes = new Crypt_AES();
+ *
+ * $aes->setKey('abcdefghijklmnop');
+ *
+ * $size = 10 * 1024;
+ * $plaintext = '';
+ * for ($i = 0; $i < $size; $i++) {
+ * $plaintext.= 'a';
+ * }
+ *
+ * echo $aes->decrypt($aes->encrypt($plaintext));
+ * ?>

+/**
+ * Pure-PHP implementations of keyed-hash message authentication codes (HMACs) and various cryptographic hashing functions.
+ *
+ * Uses hash() or mhash() if available and an internal implementation, otherwise. Currently supports the following:
+ *
+ * md2, md5, md5-96, sha1, sha1-96, sha256, sha384, and sha512
+ *
+ * If {@link Crypt_Hash::setKey() setKey()} is called, {@link Crypt_Hash::hash() hash()} will return the HMAC as opposed to
+ * the hash. If no valid algorithm is provided, sha1 will be used.
+ *
+ * PHP versions 4 and 5
+ *
+ * {@internal The variable names are the same as those in
+ * {@link http://tools.ietf.org/html/rfc2104#section-2 RFC2104}.}}
+ *
+ * Here's a short example of how to use this library:
+ * <code>
+ * <?php
+ * include('Crypt/Hash.php');
+ *
+ * $hash = new Crypt_Hash('sha1');
+ *
+ * $hash->setKey('abcdefg');
+ *
+ * echo base64_encode($hash->hash('abcdefg'));

+/**
+ * Pure-PHP implementation of RC4.
+ *
+ * Uses mcrypt, if available, and an internal implementation, otherwise.
+ *
+ * PHP versions 4 and 5
+ *
+ * Useful resources are as follows:
+ *
+ * - {@link http://www.mozilla.org/projects/security/pki/nss/draft-kaukonen-cipher-arcfour-03.txt ARCFOUR Algorithm}
+ * - {@link http://en.wikipedia.org/wiki/RC4 - Wikipedia: RC4}
+ *
+ * RC4 is also known as ARCFOUR or ARC4. The reason is elaborated upon at Wikipedia. This class is named RC4 and not
+ * ARCFOUR or ARC4 because RC4 is how it is refered to in the SSH1 specification.
+ *
+ * Here's a short example of how to use this library:
+ * <code>
+ * <?php
+ * include('Crypt/RC4.php');
+ *
+ * $rc4 = new Crypt_RC4();
+ *
+ * $rc4->setKey('abcdefgh');
+ *
+ * $size = 10 * 1024;
+ * $plaintext = '';
+ * for ($i = 0; $i < $size; $i++) {
+ * $plaintext.= 'a';
+ * }
+ *
+ * echo $rc4->decrypt($rc4->encrypt($plaintext));
+ * ?>

+ *
+ * PHP versions 4 and 5
+ *
+ * If {@link Crypt_Rijndael::setBlockLength() setBlockLength()} isn't called, it'll be assumed to be 128 bits. If
+ * {@link Crypt_Rijndael::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
+ * {@link Crypt_Rijndael::setKey() setKey()}. ie. if the key is 128-bits, the key length will be 128-bits. If it's

+ * {@link Crypt_Rijndael::setKey() setKey()} is called, again, at which point, it'll be recalculated.
+ *
+ * Not all Rijndael implementations may support 160-bits or 224-bits as the block length / key length. mcrypt, for example,
+ * does not. AES, itself, only supports block lengths of 128 and key lengths of 128, 192, and 256.
+ * {@link http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=10 Rijndael-ammended.pdf#page=10} defines the
+ * algorithm for block lengths of 192 and 256 but not for block lengths / key lengths of 160 and 224. Indeed, 160 and 224
+ * are first defined as valid key / block lengths in
+ * {@link http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=44 Rijndael-ammended.pdf#page=44}:
+ * Extensions: Other block and Cipher Key lengths.

+/**
+ * Pure-PHP arbitrary precision integer arithmetic library.
+ *
+ * Supports base-2, base-10, base-16, and base-256 numbers. Uses the GMP or BCMath extensions, if available,
+ * and an internal implementation, otherwise.
+ *
+ * PHP versions 4 and 5
+ *
+ * {@internal (all DocBlock comments regarding implementation - such as the one that follows - refer to the
+ * {@link MATH_BIGINTEGER_MODE_INTERNAL MATH_BIGINTEGER_MODE_INTERNAL} mode)
+ *
+ * Math_BigInteger uses base-2**26 to perform operations such as multiplication and division and
+ * base-2**52 (ie. two base 2**26 digits) to perform addition and subtraction. Because the largest possible
+ * value when multiplying two base-2**26 numbers together is a base-2**52 number, double precision floating
+ * point numbers - numbers that should be supported on most hardware and whose significand is 53 bits - are
+ * used. As a consequence, bitwise operators such as >> and << cannot be used, nor can the modulo operator %,
+ * which only supports integers. Although this fact will slow this library down, the fact that such a high
+ * base is being used should more than compensate.
+ *
+ * When PHP version 6 is officially released, we'll be able to use 64-bit integers. This should, once again,
+ * allow bitwise operators, and will increase the maximum possible base to 2**31 (or 2**62 for addition /
+ * subtraction).
+ *
+ * Numbers are stored in {@link http://en.wikipedia.org/wiki/Endianness little endian} format. ie.
+ * (new Math_BigInteger(pow(2, 26)))->value = array(0, 1)
+ *
+ * Useful resources are as follows:
+ *
+ * - {@link http://www.cacr.math.uwaterloo.ca/hac/about/chap14.pdf Handbook of Applied Cryptography (HAC)}
+ * - {@link http://math.libtomcrypt.com/files/tommath.pdf Multi-Precision Math (MPM)}
+ * - Java's BigInteger classes. See /j2se/src/share/classes/java/math in jdk-1_5_0-src-jrl.zip
+ *
+ * Here's an example of how to use this library:
+ * <code>
+ * <?php
+ * include('Math/BigInteger.php');
+ *
+ * $a = new Math_BigInteger(2);
+ * $b = new Math_BigInteger(3);
+ *
+ * $c = $a->add($b);
+ *
+ * echo $c->toString(); // outputs 5

+ * of the basic operations (eg. +,-,*,/) - occurs multiple times within it.
+ *
+ * Modular reductions resolve this issue. 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. This is the method that this modPow function uses.
