lightSSL

Do SSL really need to be so hard?

Ciphers: AES
Keys: ECDSA
Crypto: ASN1
Hashing: SHA3-256, SHA3-512

Compile lightSSL

rm -rf build
mkdir -p build/debug
cmake -DCMAKE_BUILD_TYPE=Debug -Bbuild/debug -DCMAKE_C_COMPILER=clang
sh ./src/scripts/gen_cert_debug.sh
make -Cbuild/debug
make -Cbuild/debug test

./scr/scripts/build.sh has those parts in it. Use the Debug type to have asserts working.

Use lightSSL

See the tests

Small example (in the src/example folder)

#include <stdio.h>

#include "../lighthash.h"

int main(void) {
  uint8_t *smurfd = (uint8_t*)"smurfd";
  char s[256] = {0}, res[] = "0x5c452b35648528cf3a00a42021489011dd455b78fc34190c7680173b2dcdcc7d61e73d4f2c51051e45d26215f\

  hash_new(s, smurfd);
  assert(strcmp(s, res) == 0);
  assert(strcmp(s + 1, res) != 0); // Assume failure
  printf("OK\n");
}
