使用盐"一词可能是指战争 在远古时代，人们会给水井或农田撒盐以减少它 好客.罗马人有时应该这样做 迦太基在公元前146年.在密码的上下文中，加盐"的密码 很难破解.

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.

显然，即使对于迦太基的原始盐渍"也没有强有力的证据( http://en. wikipedia.org/wiki/Salting_the_earth )声称，但仍然有一个有趣的假设.

Apparently, there's no strong evidence even for the original "salting" of Carthage (http://en.wikipedia.org/wiki/Salting_the_earth) claim, but an interesting hypothesis nonetheless.
