+  TITLE:=A tool for securing communications between a client and a DNS resolver
+endef
+
+define Package/dnscrypt-proxy/description
+  dnscrypt-proxy provides local service which can be used directly as your
+  local resolver or as a DNS forwarder, encrypting and authenticating requests
+  using the DNSCrypt protocol and passing them to an upstream server.
+  The DNSCrypt protocol uses high-speed high-security elliptic-curve cryptography
+  and is very similar to DNSCurve, but focuses on securing communications between
+  a client and its first-level resolver.

+  TITLE:=Resolver to IPv4 or IPv6 addresses
+endef
+
+define Package/hostip/description
+  The DNSCrypt proxy ships with a simple tool named hostip that resolves a name
+  to IPv4 or IPv6 addresses.
