About

XCA 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. Features: Start your own PKI and create all kinds of private keys, certificates, requests or CRLs Import and export them in any format like PEM, DER, PKCS#7, PKCS#12 Use them for your IPsec, OpenVPN, TLS or any other certificate based setup Manage your Smart-Cards via PKCS#11 interface Export certificates and requests as OpenSSL config file Create Subject- and/or Extension- templates to ease issuing similar certs Convert existing certificates or requests to templates Get the broad support of x509v3 extensions as flexible as OpenSSL but user friendlier Adapt the columns to have your important information at a glance
