Types

type AUMSigHash

type AUMSigHash [32]byte

AUMSigHash represents the BLAKE2s digest of an Authority Update Message (AUM), sans any signatures.

type KeyID

type KeyID []byte

KeyID references a verification key stored in the key authority. A keyID uniquely identifies a key. KeyIDs are all 32 bytes.

For 25519 keys: We just use the 32-byte public key.

Even though this is a 32-byte value, we use a byte slice because CBOR-encoded byte slices have a different prefix to CBOR-encoded arrays. Encoding as a byte slice allows us to change the size in the future if we ever need to.

type MarshaledAUM

type MarshaledAUM []byte

MarshaledAUM represents a marshaled tka.AUM.

type MarshaledSignature

type MarshaledSignature []byte

MarshaledSignature represents a marshaled tka.NodeKeySignature.

type NKSSigHash

type NKSSigHash [32]byte

NKSSigHash represents the BLAKE2s digest of a Node-Key Signature (NKS), sans the Signature field if present.

type Signature

type Signature struct {
	KeyID     KeyID  `cbor:"1,keyasint"`
	Signature []byte `cbor:"2,keyasint"`
}

Signature describes a signature over an AUM, which can be verified using the key referenced by KeyID.
