CAA Record Generator

Generate official RFC 8659 Certification Authority Authorization (CAA) DNS records. Restrict which Certificate Authorities (CAs like Let's Encrypt, DigiCert, Sectigo, Amazon) are authorized to issue SSL/TLS certificates for your domain.

Why Use This Tool?

• Prevent Rogue SSL Certificate Issuance: Block unauthorized Certificate Authorities from issuing fraudulent SSL certificates for your domain.
• Cybersecurity Compliance: Enforce domain security best practices required by enterprise security frameworks.
• Specify Wildcard SSL Rules: Configure separate rules for standard domain SSLs vs wildcard (`issuewild`) SSLs.

How to Use

1. Select Authorized Certificate Authorities (Let's Encrypt, DigiCert, Sectigo, AWS Certificate Manager).
2. Configure Wildcard Issuance (`issuewild`) policies.
3. Enter Violation Reporting Email (`iodef=mailto:security@yourdomain.com`) and copy DNS CAA records.

Real Working Example

Input:

Authorized CA: Let's Encrypt (letsencrypt.org) | Allow Wildcards: Yes | Report Email: security@devdeskapp.com

Output Result:

DNS CAA Records:
yourdomain.com. IN CAA 0 issue "letsencrypt.org"
yourdomain.com. IN CAA 0 iodef "mailto:security@devdeskapp.com"
