How it works
Fully offline — no licence server, no API calls at runtime.
Submit the form and your licence arrives instantly — no manual review, no wait.
You receive pdfluent.licence.json — a signed JSON file containing your product rights, expiry, and developer count. Treat it like an SSH private key.
{
"version": 1,
"type": "paid",
"tier": "plus",
"email": "[email protected]",
"issued_at": "2026-05-01T00:00:00Z",
"exp": null,
"signature": "ed25519:abcdef..."
}Drop pdfluent.licence.json next to your binary, or point to it via the PDFLUENT_LICENCE environment variable. The SDK never phones home — validation is fully offline.
# Option A: env var export PDFLUENT_LICENCE=/etc/pdfluent/pdfluent.licence.json # Option B: next to your binary ./my-app ./pdfluent.licence.json
On initialisation the SDK verifies the Ed25519 signature against the embedded public key. No network request, no latency, works air-gapped.
