Description
A plea...
Deanna and I have been running this site since 2008 and lately we're seeing a big increase in
users (and cost) but a decline in percentage of users who donate. Our ad-free and junkware-free
download site only works if everyone chips in to offset the revenue that ads on other sites bring
in. Please donate at the bottom of the page. Every little bit helps. Thank you so much.
Sincerely,
your Older Geeks: Randy and Deanna

SecretDNS v4.0.5

👉 A free utility for encrypted DNS and selective SNI fragmentation to help bypass website filtering.

SecretDNS combines DNS over HTTPS with SNI fragmentation to help protect DNS requests and bypass filtering based on website names. It uses a selected DNS server without changing Windows DNS settings.

DNS over HTTPS encrypts the requests your computer sends to look up website addresses. SNI fragmentation splits the part of a connection that identifies the requested website, helping bypass filtering that examines this information. SecretDNS fragments only the SNI string to minimize slowdown.

You can specify which domains receive this treatment and use a whitelist to reduce website connection problems. The program also lets you check accessed domains and combine its bypass features with proxy functionality.

To get started, click the Run button. The developer recommends selecting encrypted DNS, choosing manually specified SNI fragmentation and entering the domains you want to bypass.




Features:
• Encrypts DNS requests using DNS over HTTPS.
• Helps bypass website filtering through SNI fragmentation.
• Fragments only the SNI string to minimize speed degradation.
• Lets you apply SNI fragmentation to specified domains.
• Supports domain lists for selective DNS and fragmentation functionality.
• Uses whitelisting to help reduce website connection problems.
• Uses a selected DNS server without changing Windows DNS settings.
• Lets you check information about accessed domains.
• Can be used alongside proxy functionality.
• Provides recommended settings for encrypted DNS and selective fragmentation.
• Portable edition that runs without installation.
• Free for home, business, government and school use.

Note:
This file has five hits on VirusTotal. We have confirmed these to be false positives. The file is safe.

More info from the Older Geeks:
Some antivirus programs may flag SecretDNS because of WinDivert, a legitimate network driver that can intercept and modify internet traffic. Most detections will show the name of that driver, often describing it as riskware or a potentially unwanted tool, which does not necessarily mean a virus is present. These warnings are consistent with the capabilities of network utilities like SecretDNS.
