This project implements the AES White Box encryption scheme asoutlined in 2002 by Chow et al.
It requires the following dependencies:
Mar 11, 2008 how can i encrypt and decrypt a file using c? Kindly give me a program that will encrypt and decrypt a file.tnx! There's many ways to encrypt a file. But here is one way (this is written in C btw, can be easily converted to C.

Crypt in C and Decrypt in C# (and C). We need something to decrypt now. I will use the file that has been created in C reading all its content in specific objects. My scenario is a bit “unusual”; I want to encrypt in C and decrypt in C# without transfering anything but the encrypted data. Sep 02, 2016 C program to encrypt and decrypt text file by giving a pin or number password. FileEncryptDecrypt.cpp. In the int main function of your code, when you choose encrypt option, there's a while loop to take input in a file after giving a filename.
Whitebox cryptography implementations
This is an implementation of a white-box cryptography scheme, in particular theone from 2002, by Chow et al. For more info on white-box cryptography, see http://www.whiteboxcrypto.com/
This implementation supports:
- Generating a table that can be used by the program to encrypt and decrypt data streams
- Generating a C++ header that can be used with the C++ source file in the /genfolder to automatically create a program that implements a WBC cipher
The implementation is written in C++.The build system is CMake. It is recommended to do out-of-sourcebuilds with CMake.
The actual program can then be accessed via a command line interface.The following options are available:
--help
: Displays options--create encryption tables
Create a table for encryptionin a given file, use later with --whitebox-table--create encryption tables
Create a table for decryptionin a given file, use later with --whitebox-table--create-c-file
Create a C++ struct containing the whitebox,for embedding in other programs.--key arg
The key to use for creating the tables--whitebox-table arg
This is for encrypting/decryptinggiven an existing whitebox table--set mode ARG
Set block cipher mode, either CBC/CTR/ECB--iv arg
IV for CBC/CTR mode--set-padding ARG
Set padding mode, default PKCS/NONE for CTR--encrypt
Use table to encrypt--decrypt
Use table to decrypt--input-file ARG
input file to use, default stdin--output-file ARG
output file to use, default stdout--encrypt-state ARG
encrypt/decrypt hex AES state on commandline using whitebox table--create-external-encoding
arg Create external encodings in given file--apply-input-encoding
arg Apply input encoding to white box--apply-output-encoding
arg Apply output encoding to white box
It supports encryption and decryption with ECB, CBC and CTR modes.
