Verification of a Domain Validation (DV) certificate

By default, TLS certificates with domain DV authentication are authenticated via email sent to the authenticated domain. If your domain has no email and you cannot deliver the email, you can use an alternative certificate verification option.
Alternative domain certificate verification can be done via DNS record or uploaded to an FTP file for verification.

This verification procedure applies to the following TLS certificates:

Verification via verification email

The TLS certificate verification process consists of the given certification authority sending an email message to the preselected domain email from the TLS certificate request (admin, administrator, hostmaster, webmaster, postmaster).

In the email message, it is necessary to go through the certification authority’s website link and confirm the order with the button "I Approve".

If you do not receive the confirmation email (please check your spam), please contact us.

Alternative verification

Alternative DV certificate authentication can be used if the domain does not have an active email service or mailboxes used by the authentication authority.

Creating a DNS TXT record

For DNS verification of the domain, it is necessary to create a DNS record of the TXT type in the authenticated domain’s zone file. You can find this option in your registrar's domain administration, where you can set up DNS records.
The data for creating a TXT record will be listed in the certificate order detail and are unique to each order. You will put the already prepared records into DNS, which we will show you. In principle, this is to set a unique text in the TXT record to the _dnsauth subdomain.

An example DNS record for DNS domain verification:

_dnsauth.sslmarket.com. 3600 IN TXT pyzm2vngxyfgwbh5d04n7j9nl4zrp51v The authority will then check the TXT record in the DNS domain at regular intervals. If the TXT record is correct, it will confirm the certificate order and issue it, both will be done automatically. You will no longer have to wait for a confirmation email.

Verification by file uploaded to FTP

The file to be used for verification can be downloaded from the SSL/TLS certificate order detail. Its unique content is given by the authority and is unique to your order.

Download the fileauth.txt file (plain text) from the SSLMarket administration and upload it to the /.well-known/pki-validation/ (FTP) folder. Make sure that the file is accessible to the visitor and is not restricted, for example, by the .htaccess file.

The FTP file must be accessible from the outside for validation.
The FTP file must be accessible from the outside for validation.

The authority will automatically check the file's presence and content at regular intervals. Once it is found, it will confirm the certificate order and it will be issued.

The verification process is completed after manual (verification e-mail) or automatic (DNS record and FTP file) confirmation. The generated SSL/TLS certificate is then sent to the technical contact email, or you can obtain it at any time by logging into your customer account.
