Question

Hello
I am looking for a way to produce the same result as with MySQL’s PASSWORD function in Java.
There are a Implementation of MySQL’s PASSWORD() Function in Java code?

For example:

Password: 123
in MySQL PASSWORD (‘123 ‘) -> *23AE809DDACAF96AF0FD78ED04B6A265E05AA257

I hope you can help me

According to the answer pointed to by @ypercube, MySQL PASSWORD() is just sha1, applied twice.

Using Apache Commons Codec:

public static String MySQLPassword(String plainText) throws UnsupportedEncodingException {
    byte[] utf8 = plainText.getBytes("UTF-8");
    return "*" + DigestUtils.shaHex(DigestUtils.sha(utf8)).toUpperCase();
}

EDIT: tested, added throws clause, uppercased and a prefix “*”.

Working code (to replace shaHex() that was not working):

public static String MySQLPassword(String plainText)
                  throws UnsupportedEncodingException
{
    byte[] utf8 = plainText.getBytes("UTF-8");
    byte[] test = DigestUtils.sha(DigestUtils.sha(utf8));
    return "*" + convertToHex(test).toUpperCase();
}
