## Open Source Code Signing certificate

**What you get.** NOT free, a heavily discounted code signing certificate product for open source developers, priced "from EUR 69.00 gross" (far below standard code signing certificates). The set bundles the certificate with a cryptoCertum 3.7 IDPrime 940C mini cryptographic card and a card reader (ACS ACR39T-A1 or Omnikey 6121, depending on availability).

**Who qualifies.** Applies to the maintainer. Aimed at programmers/developers who share their software free to use or as an open source project; identity verification documents required, but no formal OSS eligibility criteria are published on the product page.

**How to apply.** Purchase the set from the Certum shop page and complete Certum's identity verification process (documents per their support pages).
