Examples of java.security.MessageDigest.digest()

java.security.MessageDigest.digest()
Completes the hash computation by performing final operations such as padding. The digest is reset after this call is made. @return the array of bytes for the resulting hash value.

    byte[] magicKeyChar = do0x0bMagic3(magicLength, magic);


    // Get password and crypt hashes as per usual.
    MessageDigest md5 = MessageDigest.getInstance("MD5");
    md5.update(password.getBytes());
    char[] result = Util.byteArrayToCharArray(md5.digest());
    char[] passwordHash = toBase64(result);


    md5.reset();
    byte[] cryptResult = crypt(password, "$1$_2S43d5f$");
    md5.update(cryptResult);

    result = Util.byteArrayToCharArray(md5.digest());
    char[] cryptHash = toBase64(result);


    // Our first authentication response is based off the password hash.
