Steps to Obtain emSign's Wildcard TLS/SSL Certificate

  • 01. DV Certificate Validation

    To get a DV Wildcard certificate, you have to prove that you are the owner of the domain using email based authentication wherein we will be sending an authentication mail to WHOIS registrar email address.

    Alternatively, we can also send authentication email to one of five pre-approved email addresses associated with the website domain, which includes:


    Alternate Domain Control Validation Methods

    CAA Email Contact, DNS TXT Record and DNS TXT Record Email Contact based authentication are the alternate methods of Domain Control Validation that you can opt for in case there is an issue with email-based authentication.

  • 02. OV Certificate Validation

    Organization validated or OV certificates require additional levels of validation compared to Domain Validated (DV) certificates and as a result provide more trust. This includes:

    • Domain Control Validation
    • Organization Authentication
    • Locality Presence
    • Telephone Verification (registered active telephone listing verification)
