TechDesk License Service — offline RSA-signed key validation. TechDesk License Service — offline RSA-signed key validation.
Key format: TDESK-<payload_b64>.<signature_b64>
payload_b64 = base64url( UTF-8 JSON bytes )
signature_b64 = base64url( RSA-SHA256 signature of those bytes )
JSON payload fields:
customer — company name
email — contact email
tier — "community" | "business" | "enterprise"
issued_at — ISO date (YYYY-MM-DD)
expires_at — ISO date (YYYY-MM-DD)
The public key below is the matching counterpart to the private key in
license_server/private_key.pem. Replace the placeholder with the real key
after running license_server/generate_keys.py for the first time.
Public key replacement steps:
1. cd license_server && python generate_keys.py
2. Copy the full contents of license_server/public_key.pem
3. Replace the PUBLIC_KEY_PEM constant below with the copied text
4. Restart the TechDesk app
The public key can only verify signatures — it cannot forge them.
It is safe to embed in the application and ship to customers.
