|
AStream |
Stream to use for reading input data for the hash value calculation. |
T5x4LongWordRecord - 160-Bit hash value for the calculation.
HashValue is an overloaded class method used to calculate a 160-bit hash value from input data provided in parameters to the method.
HashValue creates a TIdStream instance used to write the value in ASrc, and calls the overloaded Stream method.
As a class method, HashValue does not require an existing instance of TIdHash160 to perform the hash value calculation.
The stream-based variant of HasHValue is an abstract virtual method, and must be overridden in a descendant class that implements the specifics of a hashing algorithm (like TIdHashSHA1).
