C# SHA-256 vs. Java SHA-256. Different results?

Question

Java Code:

  private static final byte[] SALT = \"NJui8*&N823bVvy03^4N\".getBytes();

  public         


        

Answer 1

hexString.append(Integer.toHexString(0xFF & hash[i]));

You are building the hash string incorrectly. Integer.toHexString does not include leading zeros, so while Integer.toHexString(0xFF) == "FF", the problem is that Integer.toHexString(0x05) == "5".

Suggested correction: String.format("%02x", hash[i] & 0xFF)
