3.3 License‑Key Verification

1. Key Generation – A 25‑character alphanumeric string (e.g., ABCD‑EFGH‑IJKL‑MNOP‑QRST). The key embeds:

   • Product identifier (4K‑YT‑MP3)
   • Expiration timestamp (optional)
   • Customer‑ID hash

2. Cryptographic Scheme –

   • Public‑key (RSA‑2048) stored in the client binary.
   • Private‑key held on the licensing server.

3. Verification Flow

   1. User inputs key → client creates a SHA‑256 digest of the key + system‑generated nonce.
   2. Client sends key, nonce, digest over HTTPS to license.example.com/verify.
   3. Server validates the signature using the private key, checks expiration, and returns status, signed_token.
   4. Client stores the signed token (valid for 30 days) and enables full feature set.

4. Security Features

   • TLS 1.3 encryption for all traffic.
   • Rate limiting (max 5 attempts per minute).
   • Obfuscation of verification code via compiler‑level string encryption.
