/** * jQuery MD5 hash algorithm function *  * 	 * 		Calculate the md5 hash of a String  * 		String $.md5 ( String str ) * 	 *  * Calculates the MD5 hash of str using the » 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 * 		 * 			$.md5("I'm Persian.");  * 		 * 	Result * 		 * 			"b8c901d0f02223f9761016cfff9d68df" * 		 *  * @alias Muhammad Hussein Fattahizadeh < muhammad [AT] semnanweb [DOT] com > * @link http://www.semnanweb.com/jquery-plugin/md5.html * @see http://www.webtoolkit.info/ * @license http://www.gnu.org/licenses/gpl.html [GNU General Public License] * @param {jQuery} {md5:function(string)) * @return string */(function($){		var rotateLeft = function(lValue, iShiftBits) {		return (lValue << iShiftBits) | (lValue >>> (32 - iShiftBits));	}		var addUnsigned = function(lX, lY) {		var lX4, lY4, lX8, lY8, lResult;		lX8 = (lX & 0x80000000);		lY8 = (lY & 0x80000000);		lX4 = (lX & 0x40000000);		lY4 = (lY & 0x40000000);		lResult = (lX & 0x3FFFFFFF) + (lY & 0x3FFFFFFF);		if (lX4 & lY4) return (lResult ^ 0x80000000 ^ lX8 ^ lY8);		if (lX4 | lY4) {			if (lResult & 0x40000000) return (lResult ^ 0xC0000000 ^ lX8 ^ lY8);			else return (lResult ^ 0x40000000 ^ lX8 ^ lY8);		} else {			return (lResult ^ lX8 ^ lY8);		}	}		var F = function(x, y, z) {		return (x & y) | ((~ x) & z);	}		var G = function(x, y, z) {		return (x & z) | (y & (~ z));	}		var H = function(x, y, z) {		return (x ^ y ^ z);	}		var I = function(x, y, z) {		return (y ^ (x | (~ z)));	}		var FF = function(a, b, c, d, x, s, ac) {		a = addUnsigned(a, addUnsigned(addUnsigned(F(b, c, d), x), ac));		return addUnsigned(rotateLeft(a, s), b);	};		var GG = function(a, b, c, d, x, s, ac) {		a = addUnsigned(a, addUnsigned(addUnsigned(G(b, c, d), x), ac));		return addUnsigned(rotateLeft(a, s), b);	};		var HH = function(a, b, c, d, x, s, ac) {		a = addUnsigned(a, addUnsigned(addUnsigned(H(b, c, d), x), ac));		return addUnsigned(rotateLeft(a, s), b);	};		var II = function(a, b, c, d, x, s, ac) {		a = addUnsigned(a, addUnsigned(addUnsigned(I(b, c, d), x), ac));		return addUnsigned(rotateLeft(a, s), b);	};		var convertToWordArray = function(string) {		var lWordCount;		var lMessageLength = string.length;		var lNumberOfWordsTempOne = lMessageLength + 8;		var lNumberOfWordsTempTwo = (lNumberOfWordsTempOne - (lNumberOfWordsTempOne % 64)) / 64;		var lNumberOfWords = (lNumberOfWordsTempTwo + 1) * 16;		var lWordArray = Array(lNumberOfWords - 1);		var lBytePosition = 0;		var lByteCount = 0;		while (lByteCount < lMessageLength) {			lWordCount = (lByteCount - (lByteCount % 4)) / 4;			lBytePosition = (lByteCount % 4) * 8;			lWordArray[lWordCount] = (lWordArray[lWordCount] | (string.charCodeAt(lByteCount) << lBytePosition));			lByteCount++;		}		lWordCount = (lByteCount - (lByteCount % 4)) / 4;		lBytePosition = (lByteCount % 4) * 8;		lWordArray[lWordCount] = lWordArray[lWordCount] | (0x80 << lBytePosition);		lWordArray[lNumberOfWords - 2] = lMessageLength << 3;		lWordArray[lNumberOfWords - 1] = lMessageLength >>> 29;		return lWordArray;	};		var wordToHex = function(lValue) {		var WordToHexValue = "", WordToHexValueTemp = "", lByte, lCount;		for (lCount = 0;
