Hi every body.
My book mentions md5 one-way hash? what is it? are there md5 two-way hash,three-way hash too?
thanks and have a good weekend
MD5 is only a one-way hash. See this article for more details -
MD5 by design is a one way hash.
Developed in 1994, MD5 is a one-way hash algorithm that takes any length of data and produces a 128 bit "fingerprint" or "message digest". This fingerprint is "non-reversible", it is computationally infeasible to determine the file based on the fingerprint. This means someone cannot figure out your data based on its MD5 fingerprint.
