Compression, ZIP and Hashing

Choose the right Sharp Runtime I/O component for compression, archives or checksums.

Compute a CRC-32 checksum

#include <iostream>
#include <string>

#include "System/IO/Hashing/Crc32.hpp"

using System::IO::Hashing::Crc32;

int main()
{
    const std::string payload = "123456789";
    const auto crc = Crc32::HashToUInt32(
        reinterpret_cast<const SharpRuntime::bytecs*>(payload.data()),
        static_cast<SharpRuntime::intcs>(payload.size()));

    std::cout << std::hex << crc << '\n';
    return crc == 0xCBF43926u ? 0 : 1;
}

Rules

• Finish/flush compression streams before consuming final output.
• Treat archive entry names as untrusted paths; enforce an extraction root.
• Do not use Adler32/CRC-style hashes for authentication or password storage.
• Use Security.Cryptography for the implemented crypto hashes/HMAC/PBKDF2 surface, and document its boundaries.
