The branch stable/13 has been updated by kevans: URL: https://cgit.FreeBSD.org/src/commit/?id=e993a99fd86267a6ea6a7925bf05d3f26730ee9c commit e993a99fd86267a6ea6a7925bf05d3f26730ee9c Author: Kyle Evans <kevans@FreeBSD.org> AuthorDate: 2025-01-01 21:10:27 +0000 Commit: Kyle Evans <kevans@FreeBSD.org> CommitDate: 2025-01-11 02:48:29 +0000 secure: hook up libecc as libpkgecc libecc is not intended to be general use, other applications should really be using openssl. pkg(7) uses libecc to align with the pkg(8) project and its goals. This will be used in the upcoming support for ECC in pkg(7).
