- New PKCS#12 Digital ID File Stores the digital ID information in a file, which has the extension .pfx in Windows and .p12 in Mac OS. You can use the files interchangeably between operating systems. If you move a file from one operating system to another, Acrobat still recognizes it.
- Windows Certificate Store (Windows only) Stores the digital ID to a common location from where other Windows applications can also retrieve it.
- Type a name, email address, and other personal information for your digital ID. When you certify or sign a document, the name appears in the Signatures panel and in the Signature field.
- Choose an option from the Key Algorithm menu. The 2048-bit RSA option offers more security than 1024-bit RSA, but 1024-bit RSA is more universally compatible.
- From the Use Digital ID For menu, choose whether you want to use the digital ID for signatures, data encryption, or both.
- Type a password for the digital ID file. For each keystroke, the password strength meter evaluates your password and indicates the password strength using color patterns. Reconfirm your password.
You can export and send your certificate file to contacts who can use it to validate your signature.
