Download this repository and go to directory with project.
git clone https://github.com/GRISHNOV/RC4-PRNG.git
cd RC4-PRNG
Run the project build using the make utility.
make
Now the build folder contains the RC4_PRNG.o object file. Use it together with the RC4_PRNG.h header file from include folder to work with RC4-based pseudo-random number generator in your project.
#include <stdio.h>
#include <stdint.h>
#include <stdlib.h>
#include "RC4_PRNG.h"
int main(void)
{
uint8_t key[] = { 0x01, 0x02, 0x03, 0x04, 0x05 };
uint16_t keyLength = sizeof(key);
uint64_t streamOffset = 0;
uint64_t streamLength = 32;
uint8_t* result = getPseudoRandomBytesStream(key, keyLength, streamOffset, streamLength);
printPseudoRandomBytesStream(result, streamLength);
free(result);
return 0;
}gcc main.c RC4_PRNG.o
./a.out
