@implNote 1. We use HMAC(key, message) instead of a HASH(key + message) to avoid the length
          extension attack. To put simply, if a hacker knows the signature of the resource
          "1", and he can also know the signature of resource "12", "13", "123", and so on
          without knowledge of the key.
          <p>
          2. Use MD5 because its output size (128 bits) is small, and it is a 22-character
          Base62-encoded string.
