<h1 align="center">RC4-PRNG</h1> Implementation of RC4-based pseudo-random number generator (PRNG) in C. # Quick start 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. # Example of use ```C #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 ``` Output: ``` b2 39 63 5 f0 3d c0 27 cc c3 52 4a a 11 18 a8 69 82 94 4f 18 fc 82 d5 89 c4 3 a4 7a d 9 19 ```
