◆ SHA256Uint256()

uint256 SHA256Uint256 ( const uint256 input)

Single-SHA256 a 32-byte input (represented as uint256).

◆ TaggedHash()

CHashWriter TaggedHash ( const std::string &  tag)

Return a CHashWriter 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 CHashWriter::GetSHA256().
