DNSCrypt-Proxy 2.1.10

Tool developed to enhance the security and privacy of DNS resolutions.

Description


DNSCrypt-Proxy is a tool developed to enhance the security and privacy of DNS (Domain Name System) resolutions. It acts as a DNS client that encrypts DNS queries between the user's device and a compatible DNS server, protecting against attacks such as eavesdropping, spoofing, or data manipulation.

Main features

  • Encryption of DNS queries:
    • Utilizes encryption (based on algorithms like Salsa20 or Curve25519) to protect DNS queries, preventing internet providers, hackers, or others from intercepting the data.
    • Ensures that DNS responses are authentic and come from the configured DNS server.
  • Authentication:
    • Uses cryptographic signatures to verify the integrity and origin of DNS responses, protecting against spoofing attacks.
  • Support for multiple protocols:
    • In addition to DNSCrypt, it supports DoH (DNS over HTTPS) and DoT (DNS over TLS), which are modern secure DNS protocols.
    • Allows configuring custom DNS servers, such as Cloudflare (1.1.1.1), Google Public DNS, or others that support these protocols.
  • Flexibility and customization:
    • Can be configured to block malicious domains, ads, or trackers using blocklists.
    • Supports conditional forwarding of DNS queries based on specific rules.
    • Allows the use of anonymous DNS servers for greater privacy.
  • Local cache:
    • Stores DNS responses in cache to improve resolution speed and reduce load on DNS servers.
  • Lightweight and efficient mode:
    • Consumes few resources, making it ideal for low-capacity devices, such as routers or IoT devices.

How does it work?

  1. DNSCrypt-Proxy is installed on the user's device or on a router.
  2. It intercepts all DNS queries made by applications or the operating system.
  3. The queries are encrypted and sent to a DNS server compatible with DNSCrypt, DoH, or DoT.
  4. The server responds securely, and DNSCrypt-Proxy delivers the response to the requesting application.

Pros

  • Privacy: Prevents ISPs or third parties from monitoring the websites you access.
  • Security: Protects against attacks such as DNS cache poisoning.
  • Flexibility: Can be configured for different use cases, from basic security to blocking unwanted content.
  • Free and open-source: Available for everyone, with an active community maintaining the project.

Cons

  • Dependence on compatible servers: Not all DNS servers support DNSCrypt, although DoH and DoT are more widely accepted.
  • Initial setup: Can be complex for non-technical users, especially when configuring blocklists or advanced rules.
  • Performance: Encryption may introduce a slight latency, although local caching mitigates this.
