TaggedHash()

HashWriter TaggedHash

(

const std::string &

tag

)

Return a HashWriter primed for tagged hashes (as specified in BIP 340).

The returned object will have SHA256(tag) written to it twice (= 64 bytes). A tagged hash can be computed by feeding the message into this object, and then calling HashWriter::GetSHA256().
