◆ 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.
