This JavaScript library provides encryption for Web pages using simple, text-oriented method called column transposition. The idea is to write the plain text in block on the row-first bases. The text is then read column-first. The trick is in that the columns are not read from left to right, but in the order specified by the encryption key. Simple transliteration is applied before encryption, allso. If one is not concerned with goverement spying on them, this method may provide enough secrecy. Ideas on how to use it: encrypt address book of the high school friends or save client-side cookies encrypted with users password.
