| * jQuery MD5 hash algorithm function | |
| * | |
| * <code> | |
| * Calculate the md5 hash of a String | |
| * String $.md5 ( String str ) | |
| * </code> | |
| * | |
| * Calculates the MD5 hash of str using the ยป RSA Data Security, Inc. MD5 Message-Digest Algorithm, and returns that hash. | |
| * MD5 (Message-Digest algorithm 5) is a widely-used cryptographic hash function with a 128-bit hash value. MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of data. The generated hash is also non-reversable. Data cannot be retrieved from the message digest, the digest uniquely identifies the data. | |
| * MD5 was developed by Professor Ronald L. Rivest in 1994. Its 128 bit (16 byte) message digest makes it a faster implementation than SHA-1. | |
| * This script is used to process a variable length message into a fixed-length output of 128 bits using the MD5 algorithm. It is fully compatible with UTF-8 encoding. It is very useful when u want to transfer encrypted passwords over the internet. If you plan using UTF-8 encoding in your project don't forget to set the page encoding to UTF-8 (Content-Type meta tag). | |
| * This function orginally get from the WebToolkit and rewrite for using as the jQuery plugin. | |
| * | |
| * Example | |
| * Code | |
| * <code> | |
| * $.md5("I'm Persian."); | |
| * </code> | |
| * Result | |
| * <code> | |
| * "b8c901d0f02223f9761016cfff9d68df" | |
