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

Parameters

params: { userToken: string, partyKey: ECDSAP1PartyKeys, keyshare: ECDSAP1KeyshareV2, hexMessageHash: string }

• 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.

Returns

Promise<ECDSAP1Signature>

• Promise which resolves to the generated signature.

• The signature is a base64 encoded string.
