Node crypto MD5 encryption, and solve the problem of different Chinese

In the use of Crypto module encountered in the encryption of Chinese is not the same problem, thanks to the group inside @ ant designation

1: Solve the different problems in Chinese

function Md5pay (str) {
str = (new Buffer (str)). toString ("binary");
var ret = Crypto.createhash (' MD5 '). Update (STR). Digest ("Hex");
return ret;
}

2: Normal string encryption

function MD5 (str) {
var ret = Crypto.createhash (' MD5 '). Update (Str.tostring ()). Digest ("Hex");
return ret;
}
