The third party system publishes the encryption key as a DNS record of a third party system. The third party system receives a request to sign a message on behalf of a domain owner, the message to be sent to a recipient, and accesses an encrypted delegated private key published by the domain owner via a DNS record of the domain owner, the encrypted delegated private key encrypted using the encryption key. The third party system decrypts the encrypted delegated private key using the decryption key, and generates a signature for the message using the delegated private key. The third party system sends the signature and the message to the recipient."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure and delegated distribution of private keys via domain name service","description":"A third party system generates a public-private key pair, the public key of the key pair being an encryption key, and the private key of the key pair being a decryption key.
