Setting up your digital ID profile

The first step to be able to use Certificate Security for digitally signing PDF documents is to set up your Digital ID. Your Digital ID contains your password, along with basic information about your role. You can set up multiple profiles for yourself if you digitally sign documents in different roles.
To create a new user profile, follow these steps:

1. Choose Advanced➪Manage Digital IDs➪My Digital ID Files➪Select My Digital ID File. The Select My Digital ID dialog box opens.
2. Click the New Digital ID File button. The Create Self-Signed Digital ID dialog box appears, as shown in Figure.
3. Edit the Name, Organization Unit, Organization Name, E-mail Address, and Country/Region text boxes, if necessary (only the Name text box must be filled in), in the Digital ID Details section of the dialog box. Note the profile name that appears in the Name text box is the name that appears in the Signatures palette in Acrobat 6 and is used in the naming of the Self-Signed Digital ID filename. If you select the Enable Unicode Support check box, Acrobat displays additional text boxes for entering Unicode values for extended characters next to the ASCII versions you just entered.
4. Select an RSA algorithm (either 1024-bit or 2048-bit) in the Key Algorithm drop-down list, and then select a purpose for your Digital ID in the Use Digital ID For drop-down list. Note that 2048-bit offers more security, but 1024-bit is more compatible with current encryption technologies. Your choices are Digital Signatures, Data Encryption, or the default Digital Signatures and Data Encryption.
5. Click in the Enter a Password text box and enter a password of six characters or more.
6. Press Tab to jump to the Confirm Password text box and then reenter the password.
7. Click the Create button to open the New Self-Sign Digital ID File dialog box. By default, Acrobat names the new profile file by combining the profile name with the .pfx file extension in the Security folder within the Acrobat 6.0 folder in Windows, and the Acrobat 6.0 folder on the Macintosh. If you wish, edit the filename before clicking the Save button to save the new profile and close the Create Self-Signed Digital ID dialog box.
