Stanford Online

The certificate issued by the Stanford OpenEdX Team is signed by a gpg key so that it can be validated independently by anyone who has the OpenEdX public key. For independent verification OpenEdX uses what is called a "detached signature" meaning that the signature for the certificate is contained in a separate file with a ".sig" extension.

To complete the verification procedure you will need the following three files:

Ensure you have the pdf, the ".sig" signature file and the OpenEdX public key copied to a single directory before you begin.

Import the OpenEdX public key on OSX using GPG Keychain

Import the OpenEdX public key on Microsoft Windows using gpg4win

Verify the OpenEdX certificate using gpg on both OSX and Windows
