| Q | A | |---|---| | | Yes. The free tier caps at 500 keys/month. Paid tiers start at €199 / month for up to 10 k keys and include premium support. | | Can I migrate existing licenses to LicGen? | Absolutely. Use the /import endpoint to upload a CSV of legacy keys; the service will generate equivalent JWTs. | | What happens if a key is compromised? | Call POST /revoke with the token ID. The revocation list updates instantly and any client performing JWT verification will reject the token. | | Is there a limit on the size of metadata ? | Yes – max 2 KB per token, which is more than enough for most custom attributes. | | Do I need to host my own certificate authority? | No. LicGen uses an ECDSA‑P‑256 key pair managed by EFA. You only need to verify the public key (published at https://licgen.efa.eu/.well-known/jwks.json ). | | How does the service stay GDPR‑compliant? | All personal data (e.g., customer IDs) are stored in the EU, encrypted at rest, and never shared outside the EFA network. You can also request a full data‑export or deletion via the portal. |
Given that “EFA” appears in some older keygen releases (circa 2005–2010) for software like EFA USB tools, CAD software, or industrial control systems, it is plausible that is a search for a cracked license generator for a now-obsolete program. efa licgen 201164 link
