Performs a final update on the digest using the specified array of bytes, then completes the digest computation.

Usage

From source file:Main.java

    try {// www. j a  v a2 s.  c  o m
        MessageDigest md = MessageDigest.getInstance("MD5");

    } catch (NoSuchAlgorithmException e) {
    } catch (UnsupportedEncodingException e) {
    }
    return null;
}

From source file:Main.java

        StringBuffer sb = new StringBuffer();
        for (int i = 0; i < array.length; ++i) {
            sb.append(Integer.toHexString((array[i] & 0xFF) | 0x100).substring(1, 3));
