Bitcoin keys

Types and traits for managing Bitcoin keys.

About

The Bitcoin protocol deals with multiple formats and contexts of keys. There are legacy ECDSA keys that may or may not be compressed, X-only (Taproot) keys, private keys, etc. To avoid mixing them, this library provides multiple newtypes and additional infrastructure aiding with conversions, parsing, serializing…

The crate is no_std and doesn’t require an allocator.

Modules

bip340

Keys intended to be used in Schnorr sinatures - in P2TR.

legacy

Types handling ECDSA public keys.

Structs

Scalar

Positive 256-bit integer guaranteed to be less than the secp256k1 curve order.

XOnlyPublicKey

An x-only public key, used for verification of Schnorr signatures and serialized according to BIP-340.

Type Definitions

CompressedKeyPair

Key pair that is always serialized as compressed.

CompressedPrivateKey

Private key that is always serialized as compressed.

CompressedPublicKey

Public key that is always serialized as compressed.

LegacyKeyPair

Key pair that may be serialized as uncompressed, used in legacy addresses only.

LegacyPrivateKey

Private key that may be serialized as uncompressed, used in legacy addresses only.

LegacyPublicKey

Public key that may be serialized as uncompressed, used in legacy addresses only.
