TinyCA is a simple GUI written in Perl-Gtk to manage a small certification authority. It works as a frontend to OpenSSL. TinyCA lets you manage x509 certificates. It is possible to export data in PEM or DER format for use with servers, as PKCS#12 for use with clients, or as S/MIME certificates for use with email programs. It is also possible to import your own PKCS#10 requests and generate certificates from them. It also lets you create and manage SubCAs for more complex setups. The most important certificate extensions can be configured with the graphical frontend. English, German, Spanish, and Czech translations are included.
