Struct SighashCacheKey 

pub struct SighashCacheKey { /* private fields */ }

Legacy sighash cache key.

code_id is SHA256 of the signing script code. tx_id is SHA256 of the transaction fields the preimage still depends on (version, locktime, prevouts, sequences, outputs). Reuse requires those digests, not a 64-bit mixer of the same bytes. Other inputs’ scriptSigs are blanked in the preimage, so they are not part of tx_id.
