Q tal como estan
Pues estoy buscando el algoritmo de encripcion MD5 en php pero lo encontre en JavaScript pero no se como correrlo no se en q parte le ingreso el string a encriptar... al parecer requiere de otras funciones aca les dejo el link http://phpjs.org/functions/md5:469 haber si alguien me puede ayudar les agradecedria
Si me funciona lo puedo implementar en PHP o q tengo q hacer. gracias
este es el cod:
function md5 (str) {
var xl;
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);
}
};
