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.
e2fsimage enables the user to create and populate an ext2 filesystem image as a copy from an existing directory tree. It supports regular files, directories, soft links, hard links, and block/char special devices. The ownership of all files is changed to root, by default, while the permissions are kept.
