# crc-catalog
crc-catalog implements numerous CRCs using a bitwise algorithm implemented as a single C++ template. This can be useful for verifying existing or new CRC algorithms. Well-known CRCs are implemented as specific functions with intuitive names. There are function bindings for both the C++ as well as the C language.
Using crc-catalog is straightforward. For instance, let's calculate the standard check of CRC16/CCITT-FALSE
```C
#include
#include
#include
#include
int main()
{
const std::array crc_test_data =
{{
0x31U, 0x32U, 0x33U, 0x34U, 0x35U, 0x36U, 0x37U, 0x38U, 0x39U
}};
const std::uint16_t crc_result =
crc::catalog::crc_crc16_ccitt_false(crc_test_data.data(), crc_test_data.size());
const bool crc_result_is_ok = (crc_result == UINT16_C(0x29B1));
std::cout << "crc_result_is_ok: " << std::boolalpha << crc_result_is_ok << std::endl;
}
```
