title: CRC32 String Comparison of two files that might be identical but not sure
body: <p>I have a question regarding CRC (Checksum Redundancy Check).</p>
  
  <p>If there is a " <strong><em>slight</em></strong> " change in a file, e.g. just changing one character, will its CRC32 result be affected? Or there's a possibility that two different files have same CRC32 result?</p>
  
  <p>I have two files, which I don't know if they are completely identical, but they have the same CRC32 result.</p>
  
  <p>Your feedback is appreciated.</p>
  
  <p>Thanks</p>
