Obtain Digital Certificates

You can obtain a digital certificate either by purchasing one or by using the self-sign method.

  • To obtain a digital certificate, perform one of the following:
    • Purchase a certificate from an authority, verify and trust the authenticity of the certificate, and then use Microsoft Internet Explorer to create a PFX file based on the certificate you purchased.
    • Create a self-signed certificate using a software program such as Adobe Acrobat, Adobe Reader, OpenSSL, or OSDT as part of a PFX file, and then use the PFX file to sign PDF documents by registering it with Publisher. Bear in mind that anyone can create a self-signed certificate, so use care when verifying and trusting such a certificate.
