Obtaining the Hash Value

To obtain the hash value, a hash object must first be created using the CryptCreateHash function. This object will accumulate the data to be verified. The data is then added to the hash object with the CryptHashData function.

After the last block of data is added to the hash, the CryptGetHashParam function is used to obtain the hash value.

Once the hash value has been obtained, the hash object should be destroyed with the CryptDestroyHash function.
