使用“盐”一词可能是古代战争的参考，当时人们会把井或农田盐化，使其不那么好客。 公元前146年，罗马人有时应该对迦太基做这件事。 在密码的上下文中，“salted”密码难以破解。

显然，即使是迦太基（ http://en.wikipedia.org/wiki/Salting_the_earth ）声称的原始“盐渍化”，也没有强有力的证据，但是一个有趣的假设。

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.

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.
