Dynu gives you full control over all the DNS configurations for your domain names. You can log onto the control panel to manage your DNS records.

What is a CERT record?

CERT records, specified in RFC 4398, are used to store public key certificates and related certificate revocation lists in the DNS. They allow applications to retrieve cryptographic certificates — such as PKIX, SPKI, PGP, or X.509 — directly from a domain's DNS, which can be useful for verifying identities and securing communications.

How to add a CERT record?


To add a CERT record in the control panel, you may follow these 3 steps.

Listing Item Step 1

Log into control panel, go to Dynamic DNS Service Icon DDNS Services  and click on your domain name.

Listing Item Step 2

Go to DNS Records Icon DNS Records  to add a CERT record. The screenshot below shows how to add a CERT record for dynu.biz.

Node Name  The host name for this record. For example, leave it blank for the root domain or enter host to apply the record to host.dynu.biz.

Type  Choose "CERT - Certificate".

TTL  How long the server should cache the information. The TTL is set in seconds, 60 is 1 minute, 1800 is 30 minutes.

Certificate Type  Specifies the type of certificate being published. Common values are PKIX (X.509 as per PKIX), SPKI (Simple Public Key Infrastructure), PGP (OpenPGP packet), or IPKIX (URL of an X.509 data object).

Key Tag  A numeric identifier for the key contained in the certificate. Use 0 if no key tag applies.

Algorithm  Identifies the cryptographic algorithm used by the key. Use 0 if no algorithm is specified, or the appropriate IANA-assigned value (e.g., 5 for RSA/SHA-1, 8 for RSA/SHA-256).

Certificate  The actual certificate or certificate revocation list data, provided in hexadecimal format.
