Package: tlslookup (1.1-1)

utility like nslookup(1), but uses libnss_tls.so instead of DNS

nss-tls is an alternative, encrypted name resolving library to use with glibc, which uses DNS-over-HTTPS (DoH).

The glibc name resolver can be configured through nsswitch.conf(5) to use nss-tls instead of the DNS resolver, or fall back to DNS when nss-tls fails.

This way, all applications that use the standard resolver API (getaddrinfo(), gethostbyname(), etc'), are transparently migrated from DNS to encrypted means of name resolving, with zero application-side changes and minimal resource consumption footprint. However, nss-tls does not deal with applications that use their own, built-in DNS resolver.

This package contains the utility program to lookup DNS names using libnss-tls.
