A text decoder written in Haskell. Developed in May 2015. Comments are in Spanish.
The coding used is a biyection between characters in a way that each character of the original text has been replaced by other. The range os characters is A..Z, a..z, dots, commas, spaces and line breaks. There are not accents, numbers nor ñ. The coding change capital letters by capital letters and lower case letters by lower case letters, being consistent: if a is changed by d then A is changed by D and vice versa. The coding does not change dots, commas, spaces nor line breaks. The text to be decoded is in the file texto.txt, although any other file that follows the previous rules can be used.
frecuencias.txt and quijote.txt are auxiliary files to get the frecuency of the words. prAna.hs is the text decoder itself. Lastly, textoDescifrado.txt is the decoded text got from texto.txt using the program.
