XCA is an interface for managing RSA and DSA keys, certificates, certificate signing requests, revocation lists and templates. It uses the OpenSSL and Qt4 libraries. Certificates and requests can be created and signed and many x509v3 extensions can be added. XCA supports multiple root and intermediate Certificate authorities. The CAs can be used to create CRLs and extend certificates. The following file-formats are supported: PEM, DER, PKCS#7, PKCS#8, PKCS#10, PKCS#12, and SPKAC.
TimeGT is powerful life and task management software that keeps data in sync using a secure server. It offers numerous ways to organize tasks, ideas, and notes. It will suit a wide range of time management techniques used by different people. The following filters are available and can be used in any combination: a project tree of arbitrary depth; task life-cycle supporting Timing folders (supports GTD method); any number of Tags added to a task and used for filtering; and a Start and Due dates based Horizon filter. It keeps tasks up-to-date between any number of computers. Tasks are mediated through the dedicated secure Sync server, and are protected when they travel over the Internet (RSA of adequate length is used). Information is accessible everywhere.
