Methods

`Static`sign

sign(
    message: Uint8Array,
    address: Address,
    signingKey: Ed25519PrivateKey,
): Cip8SignResult
Signs arbitrary data and binds the signature to a Cardano address.
Parameters
- message: Uint8Array
  The raw message bytes to sign.
- address: Address
  The Cardano address object.
- signingKey: Ed25519PrivateKey
  The Ed25519 private key object.
Returns Cip8SignResult
- An object containing the COSE_Sign1 and COSE_Key buffers.
Throws
- If the signing fails or inputs are invalid.
- Defined in messageSigning/Cip8.ts:58

`Static`signEx

signEx(
    message: Uint8Array,
    keyHash: Uint8Array,
    signingKey: Ed25519PrivateKey,
): Cip8SignResult
Signs arbitrary data and binds the signature to a key hash.
Parameters
- message: Uint8Array
  The raw message bytes to sign.
- keyHash: Uint8Array
  The raw bytes of the Blake2b-224 key hash (28 bytes) to bind the signature to.
- signingKey: Ed25519PrivateKey
  The Ed25519 private key wrapper object.
Returns Cip8SignResult
- An object containing the COSE_Sign1 and COSE_Key buffers.
Throws
- If the signing fails or inputs are invalid.
