/**
|
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 |
+
* ?>
|

|
1354 |

* echo $des->encrypt($plaintext);
|
1355 |
+
* </code>
|
1356 |
+
*
|
1357 |
+
* The solution is to enable the continuous buffer. Although this will resolve the above discrepancy, it creates
|
1358 |
+
* another, as demonstrated with the following:
|
1359 |
+
*
|
1360 |
+
* <code>
|
1361 |

* $des->encrypt(substr($plaintext, 0, 8));

*
|
1368 |
+
* With the continuous buffer disabled, these would yield the same output. With it enabled, they yield different
|
1369 |

* outputs. The reason is due to the fact that the initialization vector's change after every encryption /
|
1370 |
+
* decryption round when the continuous buffer is enabled. When it's disabled, they remain constant.
|
1371 |
+
*
|
1372 |
+
* Put another way, when the continuous buffer is enabled, the state of the Crypt_DES() object changes after each
|
1373 |
+
* encryption / decryption round, whereas otherwise, it'd remain constant. For this reason, it's recommended that
|
1374 |
+
* continuous buffers not be used. They do offer better security and are, in fact, sometimes required (SSH uses them),

5 |
+
* Pure-PHP implementations of keyed-hash message authentication codes (HMACs) and various cryptographic hashing functions.
|
6 |
+
*
|
7 |
+
* Uses hash() or mhash() if available and an internal implementation, otherwise. Currently supports the following:
|
8 |
+
*
|
9 |
+
* md2, md5, md5-96, sha1, sha1-96, sha256, sha384, and sha512
|
10 |
+
*
|
11 |
+
* If {@link Crypt_Hash::setKey() setKey()} is called, {@link Crypt_Hash::hash() hash()} will return the HMAC as opposed to
|
12 |
+
* the hash. If no valid algorithm is provided, sha1 will be used.
|
13 |
+
*
|
14 |
+
* PHP versions 4 and 5
|
15 |
+
*
|
16 |
+
* {@internal The variable names are the same as those in

17 |

* {@link http://tools.ietf.org/html/rfc2104#section-2 RFC2104}.}}
|
18 |
+
*
|
19 |
+
* Here's a short example of how to use this library:
|
20 |
+
* <code>
|
21 |
+
* <?php
|
22 |
+
* include('Crypt/Hash.php');
|
23 |
+
*
|
24 |
+
* $hash = new Crypt_Hash('sha1');
|
25 |
+
*
|
26 |
+
* $hash->setKey('abcdefg');
|
27 |
+
*
|
28 |
+
* echo base64_encode($hash->hash('abcdefg'));
|
29 |
+
* ?>

* Pure-PHP implementation of RC4.
|
6 |
+
*
|
7 |
+
* Uses mcrypt, if available, and an internal implementation, otherwise.
|
8 |
+
*
|
9 |
+
* PHP versions 4 and 5
|
10 |
+
*
|
11 |
+
* Useful resources are as follows:
|
12 |
+
*
|
13 |
+
* - {@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}
|
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');
|
27 |
+
*
|
28 |
+
* $size = 10 * 1024;
|
29 |
+
* $plaintext = '';
|
30 |
+
* for ($i = 0; $i < $size; $i++) {
|
31 |
+
* $plaintext.= 'a';
|
32 |
+
* }
|
33 |
+
*
|
34 |
+
* echo $rc4->decrypt($rc4->encrypt($plaintext));
|
35 |
+
* ?>

* Say you have a 16-byte plaintext $plaintext. Using the default behavior, the two following code snippets
|
406 |
+
* will yield different outputs:
|
407 |
+
*
|
408 |
+
* <code>
|
409 |

* echo $rc4->encrypt(substr($plaintext, 0, 8));
|
410 |
+
* echo $rc4->encrypt(substr($plaintext, 8, 8));

|
412 |
+
* <code>
|
413 |
+
* echo $rc4->encrypt($plaintext);
|
414 |
+
* </code>
|
415 |
+
*
|
416 |
+
* The solution is to enable the continuous buffer. Although this will resolve the above discrepancy, it creates
|
417 |
+
* another, as demonstrated with the following:
|
418 |
+
*
|
419 |
+
* <code>
|
420 |
+
* $rc4->encrypt(substr($plaintext, 0, 8));
|
421 |
+
* echo $rc4->decrypt($des->encrypt(substr($plaintext, 8, 8)));

* <code>
|

* echo $rc4->decrypt($des->encrypt(substr($plaintext, 8, 8)));
|
425 |
+
* </code>
|
426 |
+
*
|
427 |
+
* With the continuous buffer disabled, these would yield the same output. With it enabled, they yield different
|
428 |
+
* outputs. The reason is due to the fact that the initialization vector's change after every encryption /
|
429 |
+
* decryption round when the continuous buffer is enabled. When it's disabled, they remain constant.
|
430 |
+
*
|
431 |
+
* Put another way, when the continuous buffer is enabled, the state of the Crypt_DES() object changes after each
|
432 |
+
* encryption / decryption round, whereas otherwise, it'd remain constant. For this reason, it's recommended that
|
433 |
+
* continuous buffers not be used. They do offer better security and are, in fact, sometimes required (SSH uses them),
|
434 |
+
* however, they are also less intuitive and more likely to cause you problems.

protect private keys, however, that's not what OpenSSL* does. OpenSSL protects private keys by adding

two new "fields" to the key - DEK-Info and Proc-Type. These fields are discussed here:

own implementation. ie. the implementation *is* the standard and any bugs that may exist in that

/**
|
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 |
+
* ?>

* Treat consecutive "packets" as if they are a continuous buffer.

1504 |

|
1505 |
+
* Say you have a 32-byte plaintext $plaintext. Using the default behavior, the two following code snippets
|
1506 |
+
* will yield different outputs:
|
1507 |
+
*
|
1508 |
+
* <code>
|
1509 |
+
* echo $rijndael->encrypt(substr($plaintext, 0, 16));
|
1510 |
+
* echo $rijndael->encrypt(substr($plaintext, 16, 16));
|
1511 |
+
* </code>
|
1512 |
+
* <code>
|
1513 |
+
* echo $rijndael->encrypt($plaintext);
|
1514 |
+
* </code>
|
1515 |
+
*
|
1516 |
+
* The solution is to enable the continuous buffer. Although this will resolve the above discrepancy, it creates
|
1517 |
+
* another, as demonstrated with the following:
|
1518 |
+
*
|
1519 |
+
* <code>
|
1520 |
+
* $rijndael->encrypt(substr($plaintext, 0, 16));
|
1521 |
+
* echo $rijndael->decrypt($des->encrypt(substr($plaintext, 16, 16)));
|
1522 |
+
* </code>
|
1523 |
+
* <code>
|
1524 |
+
* echo $rijndael->decrypt($des->encrypt(substr($plaintext, 16, 16)));
|
1525 |
+
* </code>
|
1526 |
+
*
|
1527 |
+
* With the continuous buffer disabled, these would yield the same output. With it enabled, they yield different
|
1528 |
+
* outputs. The reason is due to the fact that the initialization vector's change after every encryption /
|
1529 |
+
* decryption round when the continuous buffer is enabled. When it's disabled, they remain constant.
|
1530 |
+
*
|
1531 |
+
* Put another way, when the continuous buffer is enabled, the state of the Crypt_Rijndael() object changes after each
|
1532 |
+
* encryption / decryption round, whereas otherwise, it'd remain constant. For this reason, it's recommended that
|
1533 |
+
* continuous buffers not be used. They do offer better security and are, in fact, sometimes required (SSH uses them),
|
1534 |
+
* however, they are also less intuitive and more likely to cause you problems.

* Treat consecutive "packets" as if they are a continuous buffer.
|
770 |
+
*
|
771 |
+
* Say you have a 16-byte plaintext $plaintext. Using the default behavior, the two following code snippets
|
772 |
+
* will yield different outputs:
|
773 |
+
*
|
774 |
+
* <code>
|
775 |
+
* echo $des->encrypt(substr($plaintext, 0, 8));
|
776 |
+
* echo $des->encrypt(substr($plaintext, 8, 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)));
|
788 |
+
* </code>
|
789 |
+
* <code>
|
790 |
+
* 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.

* Here's a short example of how to use this library:
|
16 |
+
* <code>
|
17 |
+
* <?php
|
18 |
+
* include('Crypt/Twofish.php');

|
22 |
+
* $Twofish->setKey('12345678901234567890123456789012');
|
23 |
+
*
|
24 |
+
* $plaintext = str_repeat('a', 1024);
|
25 |
+
*
|
26 |
+
* echo $Twofish->decrypt($Twofish->encrypt($plaintext));

|
6 |

|
7 |

* PHP versions 4 and 5

8 |
+
*
|
9 |
+
* Encode and decode X.509 certificates.

10 |

|
13 |
+
*
|
14 |
+
* Note that loading an X.509 certificate and resaving it may invalidate the signature. The reason being that the signature is based on a
|
15 |
+
* portion of the certificate that contains optional parameters with default values. ie. if the parameter isn't there the default value is
|
16 |
+
* used. Problem is, if the parameter is there and it just so happens to have the default value there are two ways that that parameter can
|
17 |
+
* be encoded. It can be encoded explicitly or left out all together. This would effect the signature value and thus may invalidate the
|
18 |
+
* the certificate all together unless the certificate is re-signed.
