crypt_perm

C++ library that represents new encryption method. It uses permutations to encrypt or decrypt some data.
I've added pretty simple example of encoder that uses mentioned library.
Examle: source file - text.txt, encoded file - encoded.txt, permutation - 13562487
$ ./encoder text.txt encoded.txt 13562487 -for permutation of 8 elements
or
$ ./encoder text.txt encoded.txt "1 3 5 6 2 4 8 7" -general case, permutation of n elements(n must be divided by 2)
