macOS: delv says “no crypto support”
delv is a tool for DNS lookup and validation. I've been trying to check the DNSSEC status for some domains, on macOS however, there's just an error message.
$ delv example.org ;; none:29: no crypt support delv: No trusted keys were loaded
The source shows that this message is displayed when
DST_R_NOCRYPTO
is set, which, in turn, means
“built with no crypto support”.
Homebrew to the rescue: Since delv is part of the bind suite, the solution is to simply run
brew install bind
Now, which delv
should point to
/opt/homebrew/bin/delv
, indicating that the homebrew
version can now be used, which should solve the problem:
$ delv example.org ; fully validated example.org. 1224 IN A 93.184.215.14 example.org. 1224 IN RRSIG A 13 2 3600 20240525082652 20240504062038 771 example.org. LJ89W1W3vqKgZwaenfVsSosqslLg8srUGCMAss206Pf1TKyCrI5kEiV7 Ya8Ssl1nCfRqlSS2OJ3fjzmiTg9pNw==
