5	+ * Pure-PHP implementation of AES.
6	+ *
7	+ * Uses mcrypt, if available, and an internal implementation, otherwise.
8	+ *
9	+ * PHP versions 4 and 5
10	+ *
11	+ * If {@link Crypt_AES::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
12	+ * {@link Crypt_AES::setKey() setKey()}. ie. if the key is 128-bits, the key length will be 128-bits. If it's 136-bits
13	+ * it'll be null-padded to 160-bits and 160 bits will be the key length until {@link Crypt_Rijndael::setKey() setKey()}
14	+ * is called, again, at which point, it'll be recalculated.
15	+ *
16	+ * Since Crypt_AES extends Crypt_Rijndael, some functions are available to be called that, in the context of AES, don't
17	+ * make a whole lot of sense. {@link Crypt_AES::setBlockLength() setBlockLength()}, for instance. Calling that function,
18	+ * however possible, won't do anything (AES has a fixed block length whereas Rijndael has a variable one).
19	+ *
20	+ * Here's a short example of how to use this library:
21	+ * <code>
22	+ * <?php
23	+ * include('Crypt/AES.php');
24	+ *
25	+ * $aes = new Crypt_AES();
26	+ *
27	+ * $aes->setKey('abcdefghijklmnop');
28	+ *
29	+ * $size = 10 * 1024;
30	+ * $plaintext = '';
31	+ * for ($i = 0; $i < $size; $i++) {
32	+ * $plaintext.= 'a';
33	+ * }
34	+ *
35	+ * echo $aes->decrypt($aes->encrypt($plaintext));
36	+ * ?>

1369	+ * outputs. The reason is due to the fact that the initialization vector's change after every encryption /

9	+ * PHP versions 4 and 5

11	+ * Useful resources are as follows:

13	+ * - {@link http://www.mozilla.org/projects/security/pki/nss/draft-kaukonen-cipher-arcfour-03.txt ARCFOUR Algorithm}
14	+ * - {@link http://en.wikipedia.org/wiki/RC4 - Wikipedia: RC4}
15	+ *
16	+ * RC4 is also known as ARCFOUR or ARC4. The reason is elaborated upon at Wikipedia. This class is named RC4 and not
17	+ * ARCFOUR or ARC4 because RC4 is how it is referred to in the SSH1 specification.
18	+ *
19	+ * Here's a short example of how to use this library:
20	+ * <code>
21	+ * <?php
22	+ * include('Crypt/RC4.php');
23	+ *
24	+ * $rc4 = new Crypt_RC4();
25	+ *
26	+ * $rc4->setKey('abcdefgh');

5	+ * Pure-PHP implementation of Rijndael.
6	+ *
7	+ * Does not use mcrypt, even when available, for reasons that are explained below.
8	+ *
9	+ * PHP versions 4 and 5
10	+ *
11	+ * If {@link Crypt_Rijndael::setBlockLength() setBlockLength()} isn't called, it'll be assumed to be 128 bits. If
12	+ * {@link Crypt_Rijndael::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
13	+ * {@link Crypt_Rijndael::setKey() setKey()}. ie. if the key is 128-bits, the key length will be 128-bits. If it's
14	+ * 136-bits it'll be null-padded to 160-bits and 160 bits will be the key length until
15	+ * {@link Crypt_Rijndael::setKey() setKey()} is called, again, at which point, it'll be recalculated.
16	+ *
17	+ * Not all Rijndael implementations may support 160-bits or 224-bits as the block length / key length. mcrypt, for example,
18	+ * does not. AES, itself, only supports block lengths of 128 and key lengths of 128, 192, and 256.
19	+ * {@link http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=10 Rijndael-ammended.pdf#page=10} defines the
20	+ * algorithm for block lengths of 192 and 256 but not for block lengths / key lengths of 160 and 224. Indeed, 160 and 224
21	+ * are first defined as valid key / block lengths in
22	+ * {@link http://csrc.nist.gov/archive/aes/rijndael/Rijndael-ammended.pdf#page=44 Rijndael-ammended.pdf#page=44}:
23	+ * Extensions: Other block and Cipher Key lengths.
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));
44	+ * ?>
45	+ * </code>

1519	+ * <code>

772	+ * will yield different outputs:
773	+ *
774	+ * <code>
775	+ * echo $des->encrypt(substr($plaintext, 0, 8));

777	+ * </code>
778	+ * <code>
779	+ * echo $des->encrypt($plaintext);
780	+ * </code>
781	+ *
782	+ * The solution is to enable the continuous buffer. Although this will resolve the above discrepancy, it creates
783	+ * another, as demonstrated with the following:
784	+ *
785	+ * <code>
786	+ * $des->encrypt(substr($plaintext, 0, 8));
787	+ * echo $des->decrypt($des->encrypt(substr($plaintext, 8, 8)));

791	+ * </code>
792	+ *
793	+ * With the continuous buffer disabled, these would yield the same output. With it enabled, they yield different
794	+ * outputs. The reason is due to the fact that the initialization vector's change after every encryption /
795	+ * decryption round when the continuous buffer is enabled. When it's disabled, they remain constant.
796	+ *
797	+ * Put another way, when the continuous buffer is enabled, the state of the Crypt_DES() object changes after each
798	+ * encryption / decryption round, whereas otherwise, it'd remain constant. For this reason, it's recommended that
799	+ * continuous buffers not be used. They do offer better security and are, in fact, sometimes required (SSH uses them),
800	+ * however, they are also less intuitive and more likely to cause you problems.
