• Request payload decryption (UUID-based XOR encryption)
• Response payload decryption (OB field XOR)
• PC signature verification
• Client-side processing (no data leaves your browser)

Usage

1. Paste encrypted payload
2. Enter UUID (for request payloads)
3. View decrypted JSON and signature verification

API

import { decrypt } from "./decrypt.js";
import { decryptOb } from "./decryptOb.js";

// Request payload
const result = decrypt(encryptedPayload, uuid);

// Response payload
const { decrypted, key } = decryptOb(obField);
