Example to BCrypt hash a password.

Note: This example requires Chilkat v9.5.0.65 or greater.

Unicode C

#include <C_CkCrypt2W.h>

void ChilkatSample(void)
    {
    HCkCrypt2W crypt;
    const wchar_t *bcryptHash;

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    crypt = CkCrypt2W_Create();

    // The BCrypt cost factor (work factor) can be set to a value from 4 to 31.
    // The default value is 10.  We'll set it here explicitly to the default value
    // to make this new property known.  This line of code can be omitted
    // if the default value of 10 is desired.
    CkCrypt2W_putBCryptWorkFactor(crypt,10);

    bcryptHash = CkCrypt2W_bCryptHash(crypt,L"mySecretPassword");
    wprintf(L"BCrypt hash = %s\n",bcryptHash);

    // Sample output:
    // BCrypt hash = $2a$10$H5kIVktMGzAPKGKNAe9DVu0iwEqfhv/o4MMJ/Dzw/MPy1leOE9NOK

    // Note: Your output will be different because the BCryptHash method
    // automatically generates a random salt. 


    CkCrypt2W_Dispose(crypt);
