DNSCrypt Protocol

What is DNSCrypt Protocol?

The DNSCrypt protocol aims to enhance the security and integrity of Domain Name System (DNS) communications. It establishes a cryptographic authentication mechanism between a DNS client and a DNS resolver, ensuring that the responses received originate from the intended resolver and have not been tampered with during transit. Leveraging digital signatures, DNSCrypt validates the authenticity of the DNS data, protecting against common attacks like DNS spoofing. As an open specification with freely available reference implementations, the protocol is not tied to any specific entity, offering a vendor-neutral solution to improve the security of DNS interactions
