Public Member Functions
virtual void	reset ()=0
	Resets the instance to calculate a new hash value.
virtual void	updateHash (Span< const std::byte > input)=0
	Adds the array input to the calculated hash.
virtual void	computeHashValue (HashAlgorithmValue &hash_value)=0
	Calculates the hash value and returns it in hash_value.

Detailed Description

Context for calculating a hash incrementally.

The same context can be used multiple times by calling reset() to reset the instance.

IHashAlgorithm* algo = ...;
HashAlgorithmValue hash_value;
hash_value.reserve(algo->hashSize());
UniqueArray<std::byte> array1 = ...;
UniqueArray<std::byte> array2 = ...;
 
Ref<IHashContext> context = algo->createContext();
context->updateHash(array1);
context->updateHash(array2);
context->computeHashValue(hash_value);
