WebNov 17, 2011 · A Salt (random number) is used so that the same password does not always generate the same key. i.e. A salt is simply added to make a common password uncommon. A Salt is something we add to our hash to prevent rainbow attacks using rainbow tables which are basically just huge lookup tables that convert hashes to passwords as follows: Webfor security. In our current day and age, the cryptographic hash functions of MD5 and SHA-1 are slowly becoming phased out in favor of more secure cryptographic hash functions such as SHA-256, SHA-512 and WHIRLPOOL. In several decades, the world of cryptography will have to produce new algorithms and methods whereby security can be preserved.
