## About the product

CertySign is a digital trust platform for Kenya’s public and private sectors that supports legally binding **PKI-powered digital signatures**, **identity verification**, and **document integrity** for digital transactions.

Key capabilities include:
- **Digital signature certificates and signing workflows** to sign, verify, and manage documents using PKI.
- **e-KYC identity verification** plus **CertySign ID**, which allows a verified identity to be reused across participating organisations, with the user approving each use on their device.
- **Invoice authentication** and **blockchain-secured document integrity** features designed to help detect tampering and confirm authenticity.
- **Trusted timestamping** to prove when a document or signature existed, alongside **certificate verification** practices that include revocation-status checks (CRL and OCSP).
- **Developer APIs and SDKs** for integrating signing, verification, and identity checks into external systems (no public API documentation URL is listed).

Available on **Web** (app access) and via **API**.

Target users include government bodies, banks, SACCOs, legal firms, NGOs, SMEs, and individuals who access the service through participating organisations.

It is notable in Kenya for being developed by Reprodrive Center for Innovation Limited (RCFI), described as **CAK licensed** and aligned with the **Data Protection Act 2019**, with stated interoperability claims for systems such as Huduma Namba (NIIMS), NTSA, KRA e-TIMS, and e-Citizen.
