DNSKEY记录（RFC 4034）存储用于验证区域[[dnssec|DNSSEC]]签名的公共加密密钥。每个经DNSSEC签名的区域至少发布一个ZSK（区域签名密钥）和一个KSK（密钥签名密钥）。KSK的哈希作为DS记录发布到父区域，形成从DNS根向下的[[dnssec|信任链]]。DNSKEY记录具有特定的标志、协议和算法字段格式。
示例
Running `dig DNSKEY cloudflare.com` returns the public keys Cloudflare uses to sign its DNSSEC records — validators use these keys to verify all other DNSSEC signatures in the zone.
