## c-crypsi (Crypto Utility for C and C++)

Custom crypto utility for C/C++ based on `openssl` crypto library to make life easier

[![c-crypsi CI](https://github.com/telkomdev/c-crypsi/actions/workflows/ci.yml/badge.svg?branch=master)](https://github.com/telkomdev/c-crypsi/actions/workflows/ci.yml)

### Install

Its `header only`, just import to your project

```c

#include "crypsi.h"

int main(int argc, char** argv) {

}

```

### c-crypsi is compatible with each other with the following libraries

- NodeJs https://github.com/telkomdev/crypsi

- Golang https://github.com/telkomdev/go-crypsi

- Python https://github.com/telkomdev/pycrypsi

- C# (.NET) https://github.com/telkomdev/NetCrypsi

- Java/JVM https://github.com/telkomdev/jcrypsi

- Javascript (React and Browser) https://github.com/telkomdev/crypsi.js

### Features

- Asymmetric encryption with RSA ✔️

- Generate RSA private and public key ✔️

- Digital Signature with RSA private and public key using PSS ✔️

- Symmetric encryption with AES (GCM, CBC) ✔️

- Message authentication code with HMAC ✔️

- Generate Hash with Common DIGEST Algorithm ✔️

#### Usage

C

```c

#include 

#include 

#include 

#include "crypsi.h"

int main(int argc, char** argv) {

    printf("hello\n");

    char* message = "wuriyanto";

    unsigned char* dst_digest;

    int dst_digets_len;

    if(crypsi_sha512(message, strlen(message), &dst_digest, &dst_digets_len) != 0) {

        printf("digest error\n");

        return -1;

    }

    printf("message len: %d\n", dst_digets_len);

    printf("digest result: %s\n", dst_digest);

    free((void*) dst_digest);

    return 0;

}

```

C++

```CPP

#include 

#include "crypsi.h"

int main(int argc, char** argv)

{

    const char* message = "wuriyanto";

    unsigned char* dst_digest;

    unsigned int dst_digets_len;

    if(crypsi_sha512((const unsigned char*) message, strlen(message), &dst_digest, &dst_digets_len) != 0) {

        printf("digest error\n");

        return -1;

    }

    printf("message len: %d\n", dst_digets_len);

    printf("digest result: %s\n", dst_digest);

    

    delete dst_digest;

    return 0;

}

```
