Structs

KeychainSignature

Keychain signature wrapping another signature with a user address. This allows an access key to sign on behalf of a root account.

P256SignatureWithPreHash

P256 signature with pre-hash flag

P256SignatureWithPreHashFlags

Fieldset that facilitates compacting the parent type. Used bytes: 1 | Unused bits: 7

WebAuthnSignature

WebAuthn signature with authenticator data

WebAuthnSignatureFlags

Placeholder struct for when there is no need for a fieldset. Doesn’t actually write or read any data.

Enums

KeychainVersion

Keychain signature version.

KeychainVersionError

Keychain version validation error.

PrimitiveSignature

Primitive signature types that can be used standalone or within a Keychain signature. This enum contains only the base signature types: Secp256k1, P256, and WebAuthn. It does NOT support Keychain signatures to prevent recursion.

TempoSignature

AA transaction signature supporting multiple signature schemes

Constants

P256N_HALF

Half of the P256 curve order (n/2).

P256_ORDER

The P256 (secp256r1/prime256v1) curve order n.

SIGNATURE_TYPE_KEYCHAIN

SIGNATURE_TYPE_KEYCHAIN_V2

SIGNATURE_TYPE_P256

Signature type identifiers Note: Secp256k1 has no identifier - detected by length (65 bytes)

SIGNATURE_TYPE_WEBAUTHN

Functions

derive_p256_address

Derives a P256 address from public key coordinates

normalize_p256_s

Normalize P256 signature s value to low-s form.
