A license key generator that actually enforces something

Keys built to be checked, not just typed

Every key is 20 random characters from a 32-character Crockford base32 alphabet that leaves out the easily confused letters I, L, O and U plus a checksum character, grouped as XXXXX-XXXXX-XXXXX-XXXXX-C. That is roughly 100 bits of randomness — far beyond guessing — and the checksum lets your app catch a mistyped key before it ever calls the server.

Generate one key or five hundred

• Create up to 500 keys at once for a product, or one per order through the API.
• Choose no expiry, a fixed date, or N days after first activation — set a default per product.
• Add the customer’s e-mail and we send them the key and its validity automatically, then remind them two days before it expires.
• Export any list as CSV; spreadsheet-formula characters are neutralised for you.

Then use them

A key on its own is only a string. Foliox License ties it to a device on first use, refuses every other computer, signs every answer, and gives you a dashboard to revoke, extend or reset it. See how the whole system works.
