Install a CA security certificate

Last update 2022-09-02

The PDXpert license key file is cryptographically signed; this allows the PDXpert Server to sign PDX packages. Signed PDX packages confirm data integrity, sender authenticity, and application authenticity to supply chain partners, and supports AES256 password encryption. License key file validation requires on-going access to the Certification Authority's certificate. Where the PDXpert Server machine cannot be connected to the internet, a copy of the Certification Authority's code-signing intermediate certificate can be installed in the Windows certificate store to locally authenticate the license file.

Install the certificate§

You need local Windows administrator permissions to complete this procedure.

Install the intermediate certificate that links the USERTrust (Sectigo) RSA root certificate to PDXpert's license file code signing certificate:

  1. Download this USERTrustSectigoRSACodeSigningCA.crt certificate file to the server computer, or to another computer that can transfer the file to the server using a USB drive or local network share. Save the certificate file on the server computer's Desktop or other easy-to-find location.

    To verify the authenticity of the certificate, you can use the VirusTotal.com website to check file hashes:

    • MD5: 8b30ea5ade8b422efca635a58c6d2cc3
    • SHA-1: 2fd12800ddb15a4d6f435f55cb8313aa24c5406d
    • SHA-256: a7b50cd49b1ebbff4fd9d1e29436a998c895454cb5073cb7bbad8bdead7445ba
