Encrypting and Decrypting PDF Documents by Adobe Docs

Abstract

About the Encryption Service
The Encryption service lets you encrypt and decrypt documents. When a document is encrypted, its contents become unreadable. An authorized user can decrypt the document to obtain access to the contents. If a PDF document is encrypted with a password, the user must specify the open password before the document can be viewed in Adobe Reader or Adobe Acrobat. Likewise, if a PDF document is encrypted with a certificate, the user must decrypt the PDF document with the public key that corresponds to the certificate (private key) that was used to encrypt the PDF document.

Encrypting PDF Documents with a Password
When you encrypt a PDF document with a password, a user must specify the password to open the PDF document in Adobe Reader or Acrobat. Also, before another AEM Forms operation, such as digitally signing the PDF document, can be performed on the document, a password-encrypted PDF document must be unlocked.

Encrypting PDF Documents with Certificates
Certificate-based encryption lets you encrypt a document for specific recipients by means of public key technology. Various recipients can be given different permissions for the document. Many aspects of encryption are made possible by public key technology.
