Technitium DNS Server is an open source authoritative as well as recursive DNS server that can be used for self hosting a DNS server for privacy & security. It works out-of-the-box with no or minimal configuration and provides a user friendly web console accessible using any modern web browser.

Nobody really bothers about domain name resolution since it works automatically behind the scenes and is complex to understand. Most computer software use the operating system's DNS resolver that usually query the configured ISP's DNS server using UDP protocol. This way works well for most people but, your ISP can see and control what website you can visit even when the website employ HTTPS security. Not only that, some ISPs can redirect, block or inject content into websites you visit even when you use a different DNS provider like Google DNS or Cloudflare DNS. Having Technitium DNS Server configured to use DNS-over-TLS, DNS-over-HTTPS, or DNS-over-QUIC encrypted DNS protocols with forwarders, these privacy & security issues can be mitigated very effectively.

Be it a home network or an organization's network, having a locally running DNS server gives you more insights into your network and helps to understand it better using the DNS logs and stats. It improves overall performance since most queries are served from the DNS cache making web sites load faster by not having to wait for frequent DNS resolutions. It also gives you an additional control over your network allowing you to block domain names network wide and also allows you to route your DNS traffic securely using encrypted DNS protocols.

AES Crypt is free file encryption software available on several operating systems that uses the industry standard Advanced Encryption Standard (AES) to easily and securely encrypt files.

You do not need to be an expert to use AES Crypt, nor do you need to understand cryptography. AES Crypt is designed to be as simple to use as possible, yet still provide the strongest encryption strength available. With over a million downloads, AES Crypt has made it easy for so many people to secure information.

Using a powerful 256-bit encryption algorithm, AES Crypt can safely secure your most sensitive files. Once a file is encrypted, you do not have to worry about a person reading your sensitive information, as an encrypted file is completely useless without the password. It simply cannot be read.

AES Crypt is the perfect tool for anyone who carries sensitive information with them while traveling, uploads sensitive files to servers on the Internet, or wishes to protect sensitive information from being stolen from the home or office. AES Crypt is also the perfect solution for those who wish to backup information and store that data at a bank, in a cloud-based storage service, and any place where sensitive files might be accessible by someone else.
