Graphical certification authority is an interface for managing RSA keys and certificates, and the creation and signing of PKCS#10 requests. It uses the OpenSSL library and a Berkeley DB for key and certificate storage. It supports importing and exporting keys and PEM DER PKCS8 certificates, signing and revoking of PEM DER PKCS12, and selection of x509v3 extensions. A tree view of certificates is presented.
