Class ECDSASigner

constructor

• new ECDSASigner(did: VerifiableDID, keypair: CryptoKeyPair): ECDSASigner

  Parameters

  • did: VerifiableDID
  • keypair: CryptoKeyPair

  Returns ECDSASigner

curve

signatureType

export

• export(): CryptoKeyPair

  Export the signer as a CryptoKeyPair

  Returns CryptoKeyPair

sign

• sign(message: Uint8Array<ArrayBufferLike>): Promise<Uint8Array<ArrayBufferLike>>

  Sign a message

  Signatures are normalized to low S (s <= n/2) so each message has a single signature encoding per signing operation.

  Parameters

  • message: Uint8Array<ArrayBufferLike>

  Returns Promise<Uint8Array<ArrayBufferLike>>

toString

• toString(): DIDURL

  Returns the DID URL

  Returns DIDURL

Staticgenerate

• generate(curve: "P-256" | "P-384" | "P-521"): Promise<ECDSASigner>

  Generate a new signer

  Parameters

  • curve: "P-256" | "P-384" | "P-521"

  Returns Promise<ECDSASigner>

Staticimport

• import(key: CryptoKeyPair, did?: VerifiableDID): Promise<ECDSASigner>

  Import a signer from a CryptoKeyPair

  Parameters

  • key: CryptoKeyPair
  • Optionaldid: VerifiableDID

  Returns Promise<ECDSASigner>

StaticimportJwk

• importJwk(jwk: ECJWKPrivate, did?: VerifiableDID): Promise<ECDSASigner>

  Import a signer from a JWK

  Parameters

  • jwk: ECJWKPrivate
  • Optionaldid: VerifiableDID

  Returns Promise<ECDSASigner>
