  <p>I was reading a question about MD5, and it made me remember something that boggles me. Very simple question, and I'm sorry if it's not a good one. I just can't understand how you convert something to one thing using some algorithm, and there being no way to convert it back using the algorithm in reverse.</p>
  
  <p>So how is this possible?</p>
  
  <p>Also, since multiple strings can create the same MD5 hash, due to it being less data than the input string, how would any other hashing system be any better?</p>
