4	+ * Pure-PHP implementation of AES.
5	+ *
6	+ * Uses mcrypt, if available/possible, and an internal implementation, otherwise.
7	+ *
8	+ * PHP versions 4 and 5
9	+ *
10	+ * If {@link Crypt_AES::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
11	+ * {@link Crypt_AES::setKey() setKey()}. ie. if the key is 128-bits, the key length will be 128-bits. If it's 136-bits
12	+ * it'll be null-padded to 192-bits and 192 bits will be the key length until {@link Crypt_AES::setKey() setKey()}
13	+ * is called, again, at which point, it'll be recalculated.
14	+ *
15	+ * Since Crypt_AES extends Crypt_Rijndael, some functions are available to be called that, in the context of AES, don't
16	+ * make a whole lot of sense. {@link Crypt_AES::setBlockLength() setBlockLength()}, for instance. Calling that function,
17	+ * however possible, won't do anything (AES has a fixed block length whereas Rijndael has a variable one).
18	+ *
19	+ * Here's a short example of how to use this library:
20	+ * <code>
21	+ * <?php
22	+ * include('Crypt/AES.php');
23	+ *
24	+ * $aes = new Crypt_AES();
25	+ *
26	+ * $aes->setKey('abcdefghijklmnop');
27	+ *
28	+ * $size = 10 * 1024;
29	+ * $plaintext = '';
30	+ * for ($i = 0; $i < $size; $i++) {
31	+ * $plaintext.= 'a';
32	+ * }
33	+ *
34	+ * echo $aes->decrypt($aes->encrypt($plaintext));

4	+ * AES_Encryption
5	+ * This class allows you to easily encrypt and decrypt text in AES format
6	+ * The class automatically determines whether you need 128, 192, or 256 bits
7	+ * based on your key size. It handles multiple padding formats.
8	+ *
9	+ * Dependencies:
10	+ * This class is dependent on PHP's mcrypt extension and a class called padCrypt
11	+ *
12	+ * Information about mcrypt extension is at:
13	+ * http://us.php.net/mcrypt
14	+ *
15	+ * padCrypt class is published at:
16	+ * http://dev.strategystar.net/2011/10/php-cryptography-padding-ansi-x-923-iso-10126-pkcs7-bit-zero/
17	+ *
18	+ * The padCrypt class provides methods for padding strings with the
19	+ * common methods described at:
20	+ * http://en.wikipedia.org/wiki/Padding_%28cryptography%29
21	+ *
22	+ * -- AES_Encryption Information
23	+ *
24	+ * Key Sizes:
25	+ * 16 bytes = 128 bit encryption
26	+ * 24 bytes = 192 bit encryption
27	+ * 32 bytes = 256 bit encryption
28	+ *
29	+ * Padding Formats:
30	+ * ANSI_X.923
31	+ * ISO_10126
32	+ * PKCS7
33	+ * BIT
34	+ * ZERO
35	+ *
36	+ * The default padding method in this AES_Encryption class is ZERO padding
37	+ * ZERO padding is generally OK for paddings in messages because
38	+ * null bytes stripped at the end of a readable message should not hurt
39	+ * the point of the text. If you are concerned about message integrity,
40	+ * you can use PKCS7 instead
41	+ *
42	+ * This class does not generate keys or vectors for you. You have to
43	+ * generate them yourself because you need to keep track of them yourself
44	+ * anyway in order to decrypt AES encryptions.
45	+ *
46	+ * -- Example Usage:
47	+ *
48	+ * $key = "bac09c63f34c9845c707228b20cac5e0";
49	+ * $iv = "47c743d1b21de03034e0842352ae6b98";
50	+ * $message = "Meet me at 11 o'clock behind the monument.";
51	+ *
52	+ * $AES = new AES_Encryption($key, $iv);
53	+ * $encrypted = $AES->encrypt($message);
54	+ * $decrypted = $AES->decrypt($encrypted);

1451	+ * where, for example, the keys allready expanded,
1452	+ * keys/block_size calculated and such.
1453	+ *

1455	+ *
1456	+ * - to set $this->inline_crypt to a valid and fully working callback function
1457	+ * as a (faster) replacement for encrypt() / decrypt()

1460	+ * no matter how often _setupInlineCrypt() would be called. At some
1461	+ * point of amount they must be generic re-useable.
1462	+ *
1463	+ * - the code of _setupInlineCrypt() it self,
1464	+ * and the generated callback code,
1465	+ * must be, in following order:
1466	+ * - 100% safe
1467	+ * - 100% compatible to encrypt()/decrypt()
1468	+ * - using only php5+ features/lang-constructs/php-extensions if
1469	+ * compatibility (down to php4) or fallback is provided
1470	+ * - readable/maintainable/understandable/commented and... not-cryptic-styled-code :-)
1471	+ * - >= 10% faster than encrypt()/decrypt() [which is, by the way,
1472	+ * the reason for the existence of _setupInlineCrypt() :-)]
1473	+ * - memory-nice
1474	+ * - short (as good as possible)
1475	+ *
1476	+ * Note: - _setupInlineCrypt() is using _createInlineCryptFunction() to create the full callback function code.
1477	+ * - In case of using inline crypting, _setupInlineCrypt() must extend by the child Crypt_* class.

1481	+ * - $in (the content of $in has to en/decrypt by the generated code)
1482	+ * - The callback function should not use the 'return' statement, but en/decrypt'ing the content of $in only

5	+ * Pure-PHP arbitrary precision integer arithmetic library.
6	+ *
7	+ * Supports base-2, base-10, base-16, and base-256 numbers. Uses the GMP or BCMath extensions, if available,
8	+ * and an internal implementation, otherwise.
9	+ *
10	+ * PHP versions 4 and 5
11	+ *
12	+ * {@internal (all DocBlock comments regarding implementation - such as the one that follows - refer to the
13	+ * {@link MATH_BIGINTEGER_MODE_INTERNAL MATH_BIGINTEGER_MODE_INTERNAL} mode)
14	+ *
15	+ * Math_BigInteger uses base-2**26 to perform operations such as multiplication and division and
16	+ * base-252 (ie. two base 226 digits) to perform addition and subtraction. Because the largest possible
17	+ * value when multiplying two base-226 numbers together is a base-252 number, double precision floating
18	+ * point numbers - numbers that should be supported on most hardware and whose significand is 53 bits - are
19	+ * used. As a consequence, bitwise operators such as >> and << cannot be used, nor can the modulo operator %,
20	+ * which only supports integers. Although this fact will slow this library down, the fact that such a high
21	+ * base is being used should more than compensate.
22	+ *
23	+ * When PHP version 6 is officially released, we'll be able to use 64-bit integers. This should, once again,
24	+ * allow bitwise operators, and will increase the maximum possible base to 231 (or 262 for addition /
25	+ * subtraction).
26	+ *
27	+ * Numbers are stored in {@link http://en.wikipedia.org/wiki/Endianness little endian} format. ie.
28	+ * (new Math_BigInteger(pow(2, 26)))->value = array(0, 1)
29	+ *
30	+ * Useful resources are as follows:
31	+ *
32	+ * - {@link http://www.cacr.math.uwaterloo.ca/hac/about/chap14.pdf Handbook of Applied Cryptography (HAC)}
33	+ * - {@link http://math.libtomcrypt.com/files/tommath.pdf Multi-Precision Math (MPM)}
34	+ * - Java's BigInteger classes. See /j2se/src/share/classes/java/math in jdk-1_5_0-src-jrl.zip
35	+ *
36	+ * Here's an example of how to use this library:
37	+ * <code>
38	+ * <?php
39	+ * include('Math/BigInteger.php');
40	+ *
41	+ * $a = new Math_BigInteger(2);
42	+ * $b = new Math_BigInteger(3);
43	+ *
44	+ * $c = $a->add($b);
45	+ *
46	+ * echo $c->toString(); // outputs 5
47	+ * ?>
48	+ * </code>

1601	+ * The two most commonly used modular reductions are Barrett and Montgomery reduction. Montgomery reduction,

1604	+ * the product of two odd numbers is odd), but what about when RSA isn't used?

6	+ * Uses mcrypt, if available, and an internal implementation, otherwise.
7	+ *
8	+ * PHP versions 4 and 5
9	+ *
10	+ * Useful resources are as follows:
11	+ *
12	+ * - {@link http://en.wikipedia.org/wiki/DES_supplementary_material Wikipedia: DES supplementary material}

14	+ * - {@link http://www.cs.eku.edu/faculty/styer/460/Encrypt/JS-DES.html JavaScript DES Example}
15	+ *
16	+ * Here's a short example of how to use this library:
17	+ * <code>
18	+ * <?php
19	+ * include('Crypt/DES.php');
20	+ *
21	+ * $des = new Crypt_DES();

8	+ * PHP versions 4 and 5
9	+ *
10	+ * Useful resources are as follows:

13	+ * - {@link http://en.wikipedia.org/wiki/RC4 - Wikipedia: RC4}

15	+ * RC4 is also known as ARCFOUR or ARC4. The reason is elaborated upon at Wikipedia. This class is named RC4 and not
16	+ * ARCFOUR or ARC4 because RC4 is how it is referred to in the SSH1 specification.
17	+ *
18	+ * Here's a short example of how to use this library:
19	+ * <code>
20	+ * <?php
21	+ * include('Crypt/RC4.php');
22	+ *
23	+ * $rc4 = new Crypt_RC4();

4	+ * Pure-PHP implementation of Rijndael.
5	+ *
6	+ * Uses mcrypt, if available/possible, and an internal implementation, otherwise.
7	+ *
8	+ * PHP versions 4 and 5
9	+ *
10	+ * If {@link Crypt_Rijndael::setBlockLength() setBlockLength()} isn't called, it'll be assumed to be 128 bits. If
11	+ * {@link Crypt_Rijndael::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
12	+ * {@link Crypt_Rijndael::setKey() setKey()}. ie. if the key is 128-bits, the key length will be 128-bits. If it's
13	+ * 136-bits it'll be null-padded to 192-bits and 192 bits will be the key length until
14	+ * {@link Crypt_Rijndael::setKey() setKey()} is called, again, at which point, it'll be recalculated.
15	+ *
16	+ * Not all Rijndael implementations may support 160-bits or 224-bits as the block length / key length. mcrypt, for example,
17	+ * does not. AES, itself, only supports block lengths of 128 and key lengths of 128, 192, and 256.
18	+ * {@link http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=10 Rijndael-ammended.pdf#page=10} defines the
19	+ * algorithm for block lengths of 192 and 256 but not for block lengths / key lengths of 160 and 224. Indeed, 160 and 224
20	+ * are first defined as valid key / block lengths in
21	+ * {@link http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=44 Rijndael-ammended.pdf#page=44}:
22	+ * Extensions: Other block and Cipher Key lengths.
23	+ * Note: Use of 160/224-bit Keys must be explicitly set by setKeyLength(160) respectively setKeyLength(224).
24	+ *
25	+ * {@internal The variable names are the same as those in
26	+ * {@link http://www.csrc.nist.gov/publications/fips/fips197/fips-197.pdf#page=10 fips-197.pdf#page=10}.}}
27	+ *
28	+ * Here's a short example of how to use this library:
29	+ * <code>
30	+ * <?php
31	+ * include('Crypt/Rijndael.php');
32	+ *
33	+ * $rijndael = new Crypt_Rijndael();
34	+ *
35	+ * $rijndael->setKey('abcdefghijklmnop');
36	+ *
37	+ * $size = 10 * 1024;
38	+ * $plaintext = '';
39	+ * for ($i = 0; $i < $size; $i++) {
40	+ * $plaintext.= 'a';
41	+ * }
42	+ *
43	+ * echo $rijndael->decrypt($rijndael->encrypt($plaintext));
