Other Domain Control Validation Options

Plesk Servers > SSL
In this article we explain alternative DCV (Domain Control Validation) options.
 
Besides the traditional method of DCV using a approval email address there are 2 different types of DCV:
  • DNS CNAME-based
  • HTTP(S)-based DCV
Please Note: This article is currently only for Comodo provisioned SSL certificates
 
In order to proceed with the steps below you will need to decode your CSR showing the hash values
 
  1. Go to https://secure.comodo.com/utilities/decodeCSR.html
  2. Enter your CSR
  3. Check the box Show CSR Hashes
  4. Select Decode
  5. Copy & Paste the MD5 hash
 
Please Note: Anything below with yourdomain.com will need to be replaced with the fully qualified domain (domain.com) you are using
 
DNS CNAME-based
The CSR generated from Plesk will be submitted to Comodo hashed. The MD5 hash values provided must be entered as the DNS CNAME record for your domain. Create a CNAME record as follows based on your MD5 HASH as below:
 
<Value of MD5 hash of CSR>.yourdomain.com. CNAME <value of SHA1 hash of CSR>.comodoca.com.
Please Note: Take notice of the trailing period at the tail end of each of the TLDs as this is required to make the entry fully-qualified
 
 
HTTP(S)-based DCV
The CSR generated from Plesk will be submitted to Comodo hashed. The MD5 hash values provided must be created in a plain-text file and placed in the root of your webserver and served over HTTP-ONLY!
 
http://yourdomain.com/<Upper case value of MD5 hash of CSR>.txt
Please Note: If you have any redirects or rewrite rules this method will fail for DCV
