Grantor Certificates

Agencies are required to obtain and install a personal user authentication certificate on their application server in order to use the system-to-system feature with There are three steps to this process: (1) obtaining the correct type of digital certificate, (2) requesting installation of the certificate, and (3) authorizing the certificate in

Obtaining a Certificate

Your personal user authentication certificate must be purchased from a recognized Certificate Authority (CA) such as Comodo, DigiCert, Entrust, GoDaddy, Incommon, Symantec, or Thawte, and then sent to for installation.

Your certificate must have a 2048 bit public RSA key and use a SHA-2 based digital signature (for example SHA256RSA), so care must be taken when ordering your certificate.

Personal user authentication certificates may be difficult to find on the Certificate Authority websites, so we recommend that you contact sales departments directly and explain that you need a 2048 bit SSL client certificate that uses SHA-2. Some certificate authorities do not issue certificates valid for client authentication by default.  You may need to explicitly request a certificate with the client authentication attribute included.

Below is an example of a certificate valid for Client Authentication:

An example of a certificate valid for Client Authentication in the Certificate window, under the Details tab, for the Enhanced Key Usage Field, there is a property entry for Client Authentication available.

Additionally, you must utilize Port 443 with the SHA-2 based digital signature. Please note that all intermediate certificates in the certificate chain must also be SHA-2 in order to work with port 443.

  • Port 443 will only support:
    1. SHA-2 Certificates
    2. TLS v1.1 and TLS v1.2

Users should obtain a new SHA-2 based digital signature certificate from a recognized CA and move to port 443 immediately. Port 446 is not available in any environment as of January 1, 2016.

Note that you are responsible for monitoring your certificate expiration date in order to obtain a renewal from the CA before your certificate expires. Renewed certificates must also be sent to for installation. no longer accepts self-signed certificates as these cannot guarantee your identity and do not meet federal security standards.

Requesting Certificate Installation
