Due to the specific requirements of one of those required certificates we couldn’t use the internal services offered by SAP to sign the certificate. XCA seemed to be a light and easy way to achieve those tasks of creating and signing certificates. It also provides enough flexibility to set the specific properties required.
XCA is a tool distributed under BSD license and thus can be used freely without restriction.
The very first time XCA will be used, you will have to create a database to hold all the security assets required relevant to XCA: private and public keys, certificate signing requests, …
