MDC-2 - MDC-2DES Hashes

MDC-2DES Hashes

When MDC-2 uses the DES block cipher, the 128-bit (16-byte) MDC-2 hashes are typically represented as 32-digit hexadecimal numbers. The following demonstrates a 43-byte ASCII input and the corresponding MDC-2 hash:

MDC2("The quick brown fox jumps over the lazy dog") = 000ed54e093d61679aefbeae05bfe33a

Even a small change in the message will (with probability) result in a completely different hash, e.g. changing d to c:

MDC2("The quick brown fox jumps over the lazy cog") = 775f59f8e51aec29c57ac6ab850d58e8

The hash of the zero-length string is:

MDC2("") = 52525252525252522525252525252525
