Hash the Contents of a String (SHA256 and other hash algorithms)

See more Encryption Examples

Demonstrates how to hash the contents of a string using SHA256, SHA384, SHA512, MD2, MD5, HAVAL, RIPEMD, etc. C++

#include <CkCrypt2.h>
#include <CkByteData.h>
#include <CkStringBuilder.h>

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

    CkCrypt2 crypt;

    //  Choose the hash algorithm.
    //  Can be  "sha1", "sha256", "sha384", "sha512", "md2", "md5", "haval", "ripemd128", "ripemd160","ripemd256", or "ripemd320".
    crypt.put_HashAlgorithm("sha256");

    //  The byte representation of the string matters when hashing. 
    //  Tell Chilkat that we want to use the utf-8 byte representation.
    crypt.put_Charset("utf-8");

    CkByteData hashBytes;
    success = crypt.HashString("They who can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.",hashBytes);

    //  Let's examine the hash as a hex string.
    CkStringBuilder sb;
    sb.AppendEncoded(hashBytes,"hex");
    std::cout << "SHA256 hash = " << sb.getAsString() << "\r\n";
    }
