How to Verify a Keypair
If you are given a keypair, you can verify whether or not the secret matches the given public key:
import { createKeyPairSignerFromBytes, address } from "gill";const publicKey = address("24PNhTaNtomHhoy3fTRaMhAFCRj4uHqhZEEoWrKDbR5p");const keypairBytes = new Uint8Array([174, 47, 154, 16, 202, 193, 206, 113, 199, 190, 53, 133, 169, 175, 31, 56,222, 53, 138, 189, 224, 216, 117, 173, 10, 149, 53, 45, 73, 251, 237, 246, 15,185, 186, 82, 177, 240, 148, 69, 241, 227, 167, 80, 141, 89, 240, 121, 121,35, 172, 247, 68, 251, 226, 218, 48, 63, 176, 109, 168, 89, 238, 135,]);const signer = await createKeyPairSignerFromBytes(keypairBytes);console.log(signer.address === publicKey);// output: true
