Class PrivateKey

An Ed25519 private key in extended form, 64 bytes: the scalar kL, and kR, from which the signing nonce is derived. Bip32PrivateKey.toPrivateKey() gives one, and PrivateKey.fromSecretKey makes one from a 32-byte RFC 8032 secret key, such as a cardano-cli signing key.

Methods

sign

sign(message: Uint8Array): Uint8Array
The Ed25519 signature of message, 64 bytes.
Parameters

toBytes(): Uint8Array

A copy of the key's 64 bytes.

Returns Uint8Array

toPublicKey

toPublicKey(): PublicKey

Returns PublicKey

verify

verify(signature: Uint8Array, message: Uint8Array): boolean
Whether signature is this key's signature of message, as PublicKey.verify decides.
Parameters

- message: Uint8Array
Returns boolean

`Static`fromSecretKey

fromSecretKey(secretKey: Uint8Array): PrivateKey
The key for a 32-byte Ed25519 secret key (RFC 8032), such as a cardano-cli payment signing key: expanded with SHA-512, so it signs as RFC 8032 Ed25519 does.
Parameters
- secretKey: Uint8Array
Returns PrivateKey
