The DST API has been cleaned up, duplicate functions has been squashed
into single call (verify and verify2 functions), and couple of unused
functions have been completely removed (createctx2, computesecret,
paramcompare, and cleanup).
All DNSKEY keys are able to authenticate. The DNS_KEYTYPE_NOAUTH
(and DNS_KEYTYPE_NOCONF) flags were defined for the KEY rdata type,
and are not applicable to DNSKEY.
Previously, because the DNSKEY implementation was built on top of
KEY, the NOAUTH flag prevented authentication in DNSKEYs as well.
This has been corrected.
When writing key files to disk, use the internally stored directory.
Add an access function 'dst_key_directory()'.
Most calls to keymgr functions no longer need to provide the
key-directory value. Only 'dns_keymgr_run' still needs access to
the zone's key-directory in case the key-store is set to the built-in
key-directory.
This commit converts the license handling to adhere to the REUSE
specification. It specifically:
1. Adds used licnses to LICENSES/ directory
2. Add "isc" template for adding the copyright boilerplate
3. Changes all source files to include copyright and SPDX license
header, this includes all the C sources, documentation, zone files,
configuration files. There are notes in the doc/dev/copyrights file
on how to add correct headers to the new files.
4. Handle the rest that can't be modified via .reuse/dep5 file. The
binary (or otherwise unmodifiable) files could have license places
next to them in <foo>.license file, but this would lead to cluttered
repository and most of the files handled in the .reuse/dep5 file are
system test files.
