useECDSASignGen

Hook for generating ECDSA signature.

Import

import { useECDSASignGen } from '@silencelaboratories/react-native-duo-sdk';

---

Usage

const { 
  isLoading, 
  signature, 
  error,
  sign,
  asyncSign
} = useECDSASignGen();

sign({
  userToken,
  partyKey,
  keyshare,
  hexMessageHash,
})

---

Returns

isLoading: boolean

• Indicates if the signature generation is in progress.

signature: ECDSAP1Signature | undefined

• The generated signature.

error: DuoSDKError | undefined | unknow

• The error object if the signature generation fails.

sign: (params: { userToken: string, partyKey: ECDSAP1PartyKeys, keyshare: ECDSAP1KeyshareV2, hexMessageHash: string }) => void

• userToken: string

  • The user JWT token.

• partyKey: ECDSAP1PartyKeys

  • The party key object.

• keyshare: ECDSAP1KeyshareV2

  • The keyshare object to use for signature generation.

• hexMessageHash: string

  • Hash of a message, obtained by hashing it with a hash function and then encoding the result as a hexadecimal string.

• The function to generate the signature.

asyncSign: (params: { userToken: string, partyKey: ECDSAP1PartyKeys, keyshare: ECDSAP1KeyshareV2, hexMessageHash: string }) => Promise<ECDSAP1Signature>

• similar to sign but returns a promise which can be awaited.
