PrivateKey

A Bitcoin ECDSA private key

PublicKey

A Bitcoin ECDSA public key

Secp256k1

The secp256k1 engine, used to execute all signature operations.

SortKey

An opaque return type for PublicKey::to_sort_key

TweakedKeyPair

Tweaked BIP-340 key pair

TweakedPublicKey

Tweaked BIP-340 X-coord-only public key

XOnlyPublicKey

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

Enums

Error

Parity

Represents the parity passed between FFI function calls.

Traits
