title: UInt8 from Swift to Objective C
body: <p>I need a clarification. I'm following a tutorial on <strong>Hash sha256</strong> in <strong>Swift</strong> and my app is in <strong>Objective C</strong>. I have trouble translating this <code>UInt8</code> in Objective c. What is the equivalent in Objective C?</p>
  
  <pre><code>let rsa2048Asn1Header:[UInt8] = [
          0x30, 0x82, 0x01, 0x22, 0x30, 0x0d, 0x06, 0x09, 0x2a, 0x86, 0x48, 0x86,
          0xf7, 0x0d, 0x01, 0x01, 0x01, 0x05, 0x00, 0x03, 0x82, 0x01, 0x0f, 0x00
      ]
  </code></pre>
  
  <p>I tried this but I'm not sure it's right I'd like to have confirmation</p>
  
  <pre><code>UInt8 rsa2048AsnlHeader[] = {
           0x30, 0x82, 0x01, 0x22, 0x30, 0x0d, 0x06, 0x09, 0x2a, 0x86, 0x48, 0x86,
                   0xf7, 0x0d, 0x01, 0x01, 0x01, 0x05, 0x00, 0x03, 0x82, 0x01, 0x0f, 0x00};
