title: HSM KW command to validate ARQC
body: <p>I am trying to send <code>KW</code> command to Thales HSM, the description for one of the field data is:</p>
  
  <pre><code> ----------------------------------------------------------------
  | PAN/PAN Sequence No | 8B | this field will be fixed at 8 bytes |
   ----------------------------------------------------------------
  </code></pre>
  
  <p>Let say my data is <code>6542000000193400</code>.</p>
  
  <p>Does that means I have to convert it from hex to char?</p>
