Application/Protocol Requirements

Java Requirement

Use Java 8 or later.

Java 7 may be used but requires TLSv1.2 to be explicitly enabled by the application

TLS 1.2 Requirement

Transport Layer Security (TLS) is the most widely deployed security protocol used today for Web browsers and other applications that require data to be securely exchanged over a network.

You passively use it whenever you open a browser, and as long as you adhere to the OS/Browser requirements, you should have no browser related issues.

Below is a list of other frameworks, defining their minimum version levels to be TLS 1.2 compliant:

  • Java: use Java 8 or later. Java 7 may be used but requires TLSv1.2 to be explicitly enabled by the application
  • .NET: use .NET 4.6 or later.
  • .NET 4.5 may be used but requires TLSv1.2 to be explicitly enabled by the application.
  • .NET depends on TLS 1.2 support by the Windows OS it runs on
  • For applications using OpenSSL: use OpenSSL 1.01 or later 

Software required to view a signed document

  • Adobe Reader 9.0 or later for documents secured with AES 128-bit encryption or lower
  • Adobe Reader 10 or later for documents secured with AES 256-bit encryption

Adobe online services are available only to users 13 and older and require agreement to additional terms and the Adobe Privacy Policy. Online services are not available in all countries or languages, may require user registration, and may be discontinued or modified in whole or in part without notice. Additional fees or subscription charges may apply.
