盐"这个词的使用可能是指战争古代，人们会在水井或农田上撒盐以减少好客.罗马人有时应该这样做是为了公元前146年的迦太基.在密码的上下文中，盐渍"密码更难破解.

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，即使是迦太基的原始盐渍"(http://en.wikipedia.org/wiki/Salting_the_earth)声称，但仍然是一个有趣的假设.

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.
