1. Introduction

This application is intended as Certificate- and Key-store and as signing application issuing certificates.

All data structures (Keys, Certificate signing requests, Certificates and Templates) can be imported and exported in several formats like DER or PEM. Import means reading a file from the filesystem and storing the data structure into the database file, while exporting means to write the data structure from the database file to the filesystem to be e.g imported into an other application.

When starting the application the first time, it needs a password to encrypt the private keys in the database. After starting the application all RSA keys are hold unencrypted in the RAM of the computer. This is a security issue to be aware of.

The different parts are divided over 5 Tabs: Keys, Requests, Certificates, Templates and Revocation lists. All items can be manipulated either by a context menu available by right-clicking on the item, or by using the buttons at the right border. Every item is identified by an internal name which is unique in one tab-view and is always shown in the first column.

1.1 File formats

There are several default file-formats to exchange cryptographic data with other applications.
