How to Set Up a Digital Signature in Adobe Acrobat
If you frequently email PDF documents containing confidential information, adding a digital signature to the document can reassure the recipient of the document's authenticity. A digital signature proves that you created the document. The option to create a digital signature is built into the Adobe Acrobat application. You must access the program's security settings to create a digital signature. Once you set up the signature, you can add it to any PDF document that you create.
Launch Adobe Acrobat, then click "Document" in the main menu bar.
Select "Security Settings" from the drop-down list. The Security Settings window opens.
Click "Digital IDs" on the left side of the window.
Click the "Add ID" button, then select the checkbox next to "Create a Self-signed Digital ID for Use with Acrobat."
Click "Next," then select the checkbox next to "New PKCS#12 Digital ID File."
Click "Next" and enter your personal information into the appropriate fields. For example, enter your name and your email address. Do not edit the settings, such as the "Key Algorithm" drop-down box. Click the "Next" button. The default location of the digital signature file is in the "File Name" box. If you want to change the location, click "Browse" and then go to the location where you want to save the signature file.
Enter a password for the digital signature in the "Password" box. Re-enter the password in the "Confirm Password" box. Click the "Finish" button to complete the process.
