Dhuma 7.0.9.10
Dhuma is a customer-hosted (on-premise or cloud) web service implementing an RFC 6960 compliant OCSP server designed to scale to support large enterprises. Using a modern architecture, capable of handling an unlimited number of issuers, all with different certificate status mechanisms, Dhuma is the ideal solution to address your OCSP concerns. With high performance in mind, Dhuma is capable of caching responses and using high speed hardware security modules for signing operations.
Flexibility
Fully compliant with IETF Standards, Dhuma can be provisioned with CRLs manually or via HTTP/HTTPS and LDAP/LDAPS. Dhuma periodically polls specified repositories to obtain CRL updates on a customizable schedule; CRLs are stored in a central database that can be accessed by all Dhuma servers in a cluster. Dhuma is highly configurable, providing administrative control over nonce handling, unknown response generation, cache settings, response validity periods, and CRL polling frequency.
Providing OCSP Services for Multiple CAs Concurrently
Dhuma can provide revocation information for an unlimited number of certificate authorities from a variety of vendors.
Implementing a Large Scale OCSP Solution
Dhuma scales to support unlimited issuers and handle millions of requests.
Customizing your OCSP Deployment
Dhuma, on a per-CA basis, allows you to configure nonce handling, unknown response generation, response cache setting, validity periods, and CRL polling frequency.
