◆ copy_state()

std::unique_ptr< HashFunction > Botan::SHA_512::copy_state ( ) const

overridevirtual

Return a new hash object with the same state as *this. This allows computing the hash of several messages with a common prefix more efficiently than would otherwise be possible.

This function should be called clone but that was already used for the case of returning an uninitialized object.

Returns: new hash object

Implements Botan::HashFunction.

Create an instance based on a name, or return null if the algo/provider combination cannot be found. If provider is empty then best available is chosen.
