USING ACROBAT 9 STANDARD 233 Security Register a digital ID Register your digital ID in Acrobat before you can use it. If you have a digital ID file that doesn't appear in your list of digital IDs, you can search for the missing digital ID file. Then, add it to the list. You can identify digital ID files by their filename extensions. For PKCS #12 files, the extension is .pfx in Windows and .p12 in Mac OS. You need the digital ID password (if any) to complete this task. 1 Do one of the following: • In Acrobat, choose Advanced > Security Settings. • In Reader, choose Document > Security Settings. 2 Select Digital IDs on the left. 3 Click the Add ID button . 4 Select My Existing Digital ID From and choose one of the following options: A File Select this option if you obtained a digital ID as an electronic file. Follow the prompts to select the digital ID file, type your password, and add the digital ID to the list. A Roaming Digital ID Stored On A Server Select this option to use a digital ID that's stored on a signing server. When prompted, type the server name and URL where the roaming ID is located. A Device Connected To This Computer Select this option if you have a security token or hardware token connected to your computer. 5 Click Next, and follow the onscreen instructions to register your digital ID. Create a new digital ID If you're not using a third-party digital ID, you can create a self-signed digital ID. When you create a new digital ID, it stores an encrypted private key for signing or decrypting documents and a public key contained in a certificate. Use the certificate to validate signatures and encrypt documents. 1 Do one of the following: • In Acrobat, choose Advanced > Security Settings. • In Reader, choose Document > Security Settings. 2 Select Digital IDs on the left, and then click the Add ID button . 3 Select A New Digital ID I Want To Create Now, and click Next. 4 Specify where to store the digital ID, and click Next. New PKCS#12 Digital ID File Stores the information in a file that you can send to others. This file has a .pfx extension in Windows and .p12 in Mac OS. The files can be used 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 where other Windows applications can also retrieve it. 5 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. 6 (Optional) To use Unicode values for extended characters, select Enable Unicode Support, and then specify Unicode values in the appropriate boxes. 7 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. Last updated 9/30/2011
