pwmd
Serves XML element content over a UDS or TLS.
Pwmd allows a (libpwmd) client to store and retrieve data in an encrypted XML file via an element path. An element path is a TAB delimited string where each element name is a depth of the element tree similar to how a filesystem hierarchy is organized.
Each element of the element path may also contain an ACL to limit client access to an element path; beit a client connecting over UDS or TLS. An element may also contain a "target "attribute that resolves to another element path in the XML document similar to a symbolic link in a filesystem.
Pwmd also supports multiple connections to the same data file (with locking), obtaining a passphrase when needed via a pinentry program or key file, gpg-agent support as well as smartcards, caching options and more.
