    Function chachaEncrypt

    • Encrypt binary data with ChaCha20-Poly1305 (RFC 8439).

      Uses a random 12-byte nonce. Callers must ensure a given key is not reused for more than ~2^32 encryptions to avoid nonce collision. For high-volume random-nonce use cases, prefer xchachaEncrypt (24-byte nonce).

      Parameters

      • data: Uint8Array

        Binary data to encrypt.

      • key: Uint8Array

        32-byte encryption key.

      Returns { ciphertext: Uint8Array; nonce: Uint8Array }

      Object containing the ciphertext (with 16-byte Poly1305 tag appended) and nonce.

      If key is not exactly 32 bytes.

      import { chachaEncrypt, chachaDecrypt, randomBytes } from "@polkadot-apps/crypto";

      const key = randomBytes(32);
      const { ciphertext, nonce } = chachaEncrypt(data, key);
      const plaintext = chachaDecrypt(ciphertext, key, nonce);
