Why is a long salt better? If all you’re doing is changing the hash, a short but unique salt should be sufficient. Could someone help me out?

Anyone did look why salt are called salt???

[@zee1598]

The words salt in English, sel in French, sare in Romanian, etc. are derived from the Latin language word salarium (equivalent of salary). Salarium was the amount of money payed to Roman soldiers to buy salt.

[@zee1598]

The use of the word "salt" is probably a reference to warfare in ancient times, when people would salt the wells or farmland to make it less hospitable. The Romans are sometimes supposed to have done this to Carthage in 146 BC. In the context of passwords, a "salted" password is harder to crack. stackoverflow.com/questions/244903/why-is-a-password-salt-called-a-salt

[@sugarbooty]

Its because you add it to the password to make the hash browns better, like salt
