If you request a domain to be used in publicly trusted certificates issued by QuoVadis you are presented with several choices to validate control of the domain. This may apply to SSL/TLS certificates, or end user certificates including email addresses, such as S/MIME certificates.
BR section 3.2.2.4.7 describes a process using a Random Value published in DNS records for the domain to demonstrate control.You will be provided a Random Value by QuoVadis in the following form:
QuoVadis=000000000000-0000-0000-0000-000000000000
The Random value should be posted in DNS for the domain as follows (replacing the 000000000000-0000-0000-0000-000000000000 with the Random Value you were given):
example.com. IN TXT "QuoVadis=000000000000-0000-0000-0000-000000000000"
Important Note: If the option is available, QuoVadis highly recommends setting the TTL to 1800 for all TXT records.
Setting a longer TTL may delay the time it takes for your domain to be validated.
Alternatively, you can prefix “_dnsauth” to the record if there is a conflict with an existing CNAME record as follows:
_dnsauth.example.com. IN TXT "QuoVadis=000000000000-0000-0000-0000-000000000000"
The Random Value provided by QuoVadis is valid for 30 days, and validation must reoccur according to the applicable requirements of the certificate type (detailed in Section 4.2.1 of the Baseline Requirements or Section 11.14.3 of the EV Guidelines).
