Crate silent_payments_core 

silent-payments-core

Core primitives for BIP 352 Silent Payments: error types, key newtypes with zeroization, address encoding, input classification, and cryptographic safety wrappers.

This crate provides type-safe wrappers around bdk-sp with explicit error handling, zeroized secret key storage, and SEC-04 compliance (all EC operations via bitcoin::secp256k1).

Main types

• SpAddress – BIP 352 Silent Payment address (parse, encode, construct)
• ScanPublicKey / ScanSecretKey – receiver’s scan key pair
• SpendPublicKey / SpendSecretKey – receiver’s spend key pair
• ClassifiedInput / SpInputType – transaction input classification
• compute_shared_secret, compute_output_pubkey – ECDH and output derivation
