TXTCOD 4.7.1b

TXTCOD is an encoding module using the SAC system. SYNOPSIS use TXTCOD; TXTCOD::codage($source, $destination, < $file.cod >, < $algorithm.alc >, < $param >); $param = TXTCOD::decodage($source, $destination, $file.cod, < $algorithm.alc >); $file.cod = TXTCOD::createcod; TXTCOD 4.7 encodes files with the SAC system, 2.4 version.. The SAC system consists in several algorithms : a default algorithm who can be remplaced by user-written algorithms. Every algorithm uses a .cod file generated by the module and who contains a list of random numbers used by the module in order to ensure a maximal protection. B<< A file must be encoded with the same algorithm and the same .cod file !!! . >> This version of the SAC system can encode any type of file (binary files, text) and recognizes automatically their type. In the first part you will see the modules how-to and in the second part how to program an algorithm. FIRST PART : TXTCOD Module These functions will be accessible after you have typed B<< use TXTCOD; >> 1) Encoding You call the encoding function by typing : TXTCOD::codage($source, $destination, < $file.cod >, < $algorithm.alc >, < $param >); This function doesnt return any value. $source is the file you want to encode. $destination is the file where TXTCOD will send the result of the encoding. These two parameters are B<< obligatory >>. $file.cod is the .cod file who is indispensable for the encoding and the decoding. If you dont specify this parameter, will search a "[year].cod" file, for example "2003.cod". A .cod file MUST be changed every year at least in order to assure an optimal protection. $algorithm.alc is the used algorithm. If you dont put anything, TXTCOD will use the default algorithm. $param is an user-defined parameter who wont be crypted. 2) Decoding You call the decoding function by typing : $param = TXTCOD::decodage($source, $destination, $file.cod, <$algorithm.alc>); $source in the file you want to decode. $destination is the result of the decoding $file.cod et $algorithm.alc -> see the encoding function description. The returned value is the parameter you optionnally defined while the encoding and which isnt crypted. 3) .cod files creation To create a .cod file type : $file.cod = TXTCOD::createcod; The returned value is the files name ("[year].cod").
