dnsimple / dns_erlang Goto Github PK

All records have the form key_tag while DS and CDS records use keytag as the field name. Should make this consistent.

It appears that OTP20 deprecated crypto:sha/1 in favor of crypto:hash/2

when running
make test

I get one failing test

Investigation

Oddly, it appears that crypto:sha/1 is undefined when it is trying to be accessed:
ih(?DNSSEC_NSEC3_ALG_SHA1, Salt, X, I) -> ih(fun crypto:sha/1, Salt, X, I).
This creates an anonymous function #Fun<crypto.sha.1>. Then, when we try to execute it

ih(H, Salt, X, 0) when is_function(H, 1) -> H([X, Salt]);
ih(H, Salt, X, I) when is_function(H, 1) -> ih(H, Salt, H([X, Salt]), I - 1);
ih(?DNSSEC_NSEC3_ALG_SHA1, Salt, X, I) -> ih(fun crypto:sha/1, Salt, X, I).

It triggers the undef.

It appears that OTP20 deprecated crypto:sha/1 in favor of crypto:hash/2

The name dns is already taken in hex. Due to this, the application will need to be renamed.

Any chance the readme could be updated with a bit of documentation? This library seems great but I'm not sure where to start with it :)

The link "Online documentation" on Hex yields 404.

Is it intentional that the define for it is missing?

Given the fingerprint 8544BD5B4902151F80391563A6511FD864489763, the output when queried with dig is 38353434424435423439303231353146383033393135363341363531 314644383634343839373633

Any thoughts on what might be happening here?
