dnscrypt-proxy acts as a DNS proxy between a regular client, like a DNS cache or an operating system stub resolver, and a DNSCrypt-aware resolver, like OpenDNS. The DNSCrypt protocol focuses on securing communications between a client and its first-level resolver. While not providing end-to-end security, it protects the local network (which is often the weakest link in the chain) against man-in-the-middle attacks. It also provides some confidentiality to DNS queries.
Metasploit Express is security software for security professionals in enterprises and government agencies who need to carry out penetration tests against their systems quickly and easily. It adds a graphical user interface to the Metasploit Framework, the de-facto leader in pentesting tools, and automates many of the tasks that otherwise require custom scripting, such as smart brute forcing, evidence collection, and reporting.
