EverCrack Cipher Language Identification Tool

The EverCrack Language Identification Tools works by calculating the Index of

Coincidence of the cipher text [the Index of Coincidence is a value derived

from frequency analysis that determining the relative distribution of letters

in the cipher text .

Each language has a specific IOC because the letters of each language have a

specific frequency distribution.  The IOC value [of the cipher text] is com-

pared to the IOC values of different languages; The language which varies the

least from the IOC value of the cipher text is chosen as the most probable.

English .06689
German .07666
Spanish .07661
French .07460
Swedish .06448
Italian .07329
