Certification Practices and Certificate Profiles

Signature Verification Example:

In order to verify the digital signature by the Virginia Tech Root CA on the Virginia Tech User CA Certification Practices Document, you must have software installed which will allow you to process a digitally signed PKCS#7 document. For example if you have OpenSSL installed, you can verify the digital signature as follows:

  1. Download the PKCS#7 Digitally Signed PDF Document to a file named vtucps.sig
  2. Download the Virginia Tech Root CA certificate in PEM format to a file named cacert.pem
  3. Execute the following OpenSSL command to verify the digital signature:
    openssl smime -verify -inform PEM -in .\vtucps.sig -CAfile .\cacert.pem -out .\vtucps.pdf -signer .\cacert.pem
  4. You should see the message "Verification successful". A clear text version of the Virginia Tech User CA Certification Practices will be created in the file vtucps.pdf
