title: MD5 is 128 bits but why is it 32 characters?
body: <p>I read some docs about md5, it said that its 128 bits, but why is it 32 characters? I can't compute the characters.</p>
  
  <ul>
  <li>1 byte is 8 bits</li>
  <li>if 1 character is 1 byte</li>
  <li>then 128 bits is 128/8 = 16 bytes right?</li>
  </ul>
  
  <p>EDIT:</p>
  
  <p>SHA-1 produces 160 bits, so how many characters are there?</p>
