xca

This application is intended for creating and managing X.509 certificates, certificate requests, RSA, DSA and EC private keys, Smartcards and CRLs.
Everything that is needed for a CA is implemented.
All CAs can sign sub-CAs recursively. These certificate chains are shown clearly.
For an easy company-wide use there are customiseable templates that can be used for certificate or request generation.

All cryptographic data is stored in a SQL database.
