Editing MD2 (hash function) (section)

==MD2 hashes==
The 128-bit (16-byte) MD2 hashes (also termed ''message digests'') are typically represented as 32-digit [[hexadecimal]] numbers. The following demonstrates a 43-byte [[ASCII]] input and the corresponding MD2 hash:

  MD2("The quick brown fox jumps over the lazy {{Background color|#87CEEB|d}}og") = 
  03d85a0d629d2c442e987525319fc471

As the result of the [[avalanche effect]] in MD2, even a small change in the input message will (with overwhelming probability) result in a completely different hash. For example, changing the letter {{mono|d}} to {{mono|c}} in the message results in:

  MD2("The quick brown fox jumps over the lazy {{Background color|#87CEEB|c}}og") = 
  6b890c9292668cdbbfda00a4ebf31f05

The hash of the zero-length string is:

  MD2("") = 
  8350e5a3e24c153df2275c9f80692773
