I am trying to make a program that takes an encrypted file (DES) and decrypts the file.
I have managed to write a program that can encrypt and decrypt using standard DES. However, the encrypted files it produces contain NON alpha numeric characters in the file. I am still able to decrypt that file and get the correct original file, BUT I have then tested it with some test data that I have, which uses STANDARD DES IMPLEMENTATION and the sample encrypted data doesn't contain any NON alpha numeric data.
I am looking for A STANDARD DES (and 3DES) library for C++ that will take a file and encrypt or decrypt it, but not use NON alphanumeric characters.
Am I doing something wrong? or is it just how the DES is implemented in the library?
If you need anymore info let me know.
