Compute Glacier SHA256 Linear Hash of a File

See more Amazon Glacier Examples

Computes the Amazon Glacier SHA256 linear hash for a file. C++

#include <CkCrypt2.h>

void ChilkatSample(void)
    {
    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkCrypt2 crypt;

    // The "linear hash" is simply the SHA256 hash of the file bytes.
    crypt.put_HashAlgorithm("sha256");

    // Return the hash in lowercase hexidecimal format.
    crypt.put_EncodingMode("hexlower");

    const char *linearHashHex = crypt.hashFileENC("qa_data/jpg/penguins.jpg");
    std::cout << "SHA256 linear hash = " << linearHashHex << "\r\n";
    }
