Ecwid Ecommerce Shopping Cart

Version Description

Added compatibility with the "Add Meta Tags" plugin. The "Add Meta Tags" plugin is a popular tool to set SEO meta tags on site pages. Previously it rewrote the titles and description that Ecwid generated for search engines on your site. It's now fixed so if you use the plugin, everything should work fine and Google will index your products pages properly.
Fixed a problem in the recently viewed products widget caused by Autoptimize plugin. Previously, if Autoptimize plugin is used on the site, the recently viewed products widget reset the displayed products when page reloads. We fixed that.
A few internal improvements to make the plugin more stable and ready for the upcoming cool features. Stay tuned! More updates are coming.

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	+ * NOTE: Since AES.php is (for compatibility and phpseclib-historical reasons) virtually
11	+ * just a wrapper to Rijndael.php you may consider using Rijndael.php instead of
12	+ * to save one include_once().
13	+ *
14	+ * If {@link Crypt_AES::setKeyLength() setKeyLength()} isn't called, it'll be calculated from
15	+ * {@link Crypt_AES::setKey() setKey()}. ie. if the key is 128-bits, the key length will be 128-bits. If it's 136-bits
16	+ * it'll be null-padded to 192-bits and 192 bits will be the key length until {@link Crypt_AES::setKey() setKey()}
17	+ * is called, again, at which point, it'll be recalculated.
18	+ *
19	+ * Since Crypt_AES extends Crypt_Rijndael, some functions are available to be called that, in the context of AES, don't
20	+ * make a whole lot of sense. {@link Crypt_AES::setBlockLength() setBlockLength()}, for instance. Calling that function,
21	+ * however possible, won't do anything (AES has a fixed block length whereas Rijndael has a variable one).
22	+ *
23	+ * Here's a short example of how to use this library:
24	+ * <code>
25	+ * <?php
26	+ * include 'Crypt/AES.php';
27	+ *
28	+ * $aes = new Crypt_AES();
29	+ *
30	+ * $aes->setKey('abcdefghijklmnop');
31	+ *
32	+ * $size = 10 * 1024;
33	+ * $plaintext = '';
34	+ * for ($i = 0; $i < $size; $i++) {
35	+ * $plaintext.= 'a';
36	+ * }
37	+ *
38	+ * echo $aes->decrypt($aes->encrypt($plaintext));
39	+ * ?>

2023	+ * where, for example, the keys allready expanded,

2028	+ * - to set $this->inline_crypt to a valid and fully working callback function
2029	+ * as a (faster) replacement for encrypt() / decrypt()

2033	+ * point of amount they must be generic re-useable.
2034	+ *
2035	+ * - the code of _setupInlineCrypt() it self,
2036	+ * and the generated callback code,
2037	+ * must be, in following order:
2038	+ * - 100% safe
2039	+ * - 100% compatible to encrypt()/decrypt()
2040	+ * - using only php5+ features/lang-constructs/php-extensions if
2041	+ * compatibility (down to php4) or fallback is provided
2042	+ * - readable/maintainable/understandable/commented and... not-cryptic-styled-code :-)
2043	+ * - >= 10% faster than encrypt()/decrypt() [which is, by the way,
2044	+ * the reason for the existence of _setupInlineCrypt() :-)]
2045	+ * - memory-nice
2046	+ * - short (as good as possible)
2047	+ *
2048	+ * Note: - _setupInlineCrypt() is using _createInlineCryptFunction() to create the full callback function code.
2049	+ * - In case of using inline crypting, _setupInlineCrypt() must extend by the child Crypt_* class.
2050	+ * - The following variable names are reserved:
2051	+ * - $_* (all variable names prefixed with an underscore)
2052	+ * - $self (object reference to it self. Do not use $this, but $self instead)
2053	+ * - $in (the content of $in has to en/decrypt by the generated code)
2054	+ * - The callback function should not use the 'return' statement, but en/decrypt'ing the content of $in only

3	+ /**
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}.}}

110	+ = 3.4.4 =
111	+ - Added compatibility with the "Add Meta Tags" plugin. The "Add Meta Tags" plugin is a popular tool to set SEO meta tags on site pages. Previously it rewrote the titles and description that Ecwid generated for search engines on your site. It's now fixed so if you use the plugin, everything should work fine and Google will index your products pages properly.
112	+ - Fixed a problem in the recently viewed products widget caused by Autoptimize plugin. Previously, if Autoptimize plugin is used on the site, the recently viewed products widget reset the displayed products when page reloads. We fixed that.
113	+ - A few internal improvements to make the plugin more stable and ready for the upcoming cool features. Stay tuned! More updates are coming.
