Adobe Acrobat lets your create e-signature certificates in PFX format to secure and encrypt sensitive information. This feature essentially adds your e-signature to a sensitive document and creates a new file with your "digital ID" to store all encryption data and information that you can send and share with other authorized users.
Launch Adobe Acrobat from the Start menu. Please note this software is essential to creating a certificate in PFX format. If you do not have a copy yet, you can download it from Adobe's website (see Resources).
Click on the "Advanced" tab and select "Security Settings."
Click to choose "Digital IDs" to your left. Hit "Add ID."
Click to choose "A new digital ID I want to create now." Hit "Next." Browse to navigate to a secured location where you wish to save the "Digital ID." Hit "Next."
Click to choose "New PKCS#12 digital ID file" to save the encryption data in a PFX file. This will ensure that you can send and share the file with other authorized users.
