Calculate hash value with salt (pSalt,nSaltLen) prepended to password (pInput,nLength) and repeated iterations run if nSpinCount>0.
This implements the algorithms as specified in https://msdn.microsoft.com/en-us/library/dd920692 or https://msdn.microsoft.com/en-us/library/dd924776 and https://msdn.microsoft.com/en-us/library/dd925430
| pSalt | may be nullptr thus no salt prepended |
| nSpinCount | If >0, repeat nSpinCount iterations. For each iteration, the previous iteration's result plus a 4 byte value (0-based, little endian) containing the number of the iteration prepended or appended to the hash value is the input for the next iteration. |
| eIterCount | If IterCount::APPEND, append iteration count as per https://msdn.microsoft.com/en-us/library/dd920692 If IterCount::PREPEND, prepend iteration count as per https://msdn.microsoft.com/en-us/library/dd924776 and https://msdn.microsoft.com/en-us/library/dd925430 If IterCount::NONE, do not add the iteration count to hash iterations. |
