The maintainer of DNSCrypt stopped supporting it, closed the repository on GitHub and put the domain on sale. The repository has already been cloned and is now maintained by Dyne. Unfortunately, they do not plan to add any new features, so DNSCrypt is abandoned in favor of the "DNS over TLS" standard.
Good news from Adguard DNS!
Instead of a regular client-server interaction protocol, Adguard DNS now allows you to use a specific encrypted protocol - DNSCrypt. Now all requests between your computer and Adguard DNS servers can be encrypted with secure elliptic curve cryptography to protect them from possible interception and subsequent eavesdropping and alteration by any intruder, even if it is your ISP. It needs a little configuration though.
