title: What’s the difference between md5(), crc32() and sha1() crypto on PHP?
body: <p>The difference is in the length they generate.</p>
  
  <p>crc32() gives 32 bit code</p>
  
  <p>sha1() gives 128 bit code</p>
  
  <p>md5() gives 160 bit code</p>
  
  <p>is it right?? or Is there any more differences among them?</p>
