Rainbow PDF Digital Signature Details & Specs

How does Rainbow PDF Digital Signature Work?
Rainbow PDF Digital Signature applies Digital Signatures to control access to a document. It uses asymmetric cryptology to simulate the security properties of a signature in digital rather than in written form. Public and private key encryption is validated through the Windows Certificate Store to ensure legitimacy.

Easy to use Graphic User Interface allows signature options to be changed in a familiar environment.

You can change settings in 4 groups by clicking the appropriate tabs: Signature, Appearance/Certificates, Security and Verifying

By clicking the "Save & Quit" button, the contents set by the GUI Signature Setting are saved in the configuration file.


Rainbow PDF Digital Signature can sign and control document access three ways:

• Apply a digital signature to an existing PDF A sender applies a private key signature that gets sent with a recipient’s public key information. That document can only be opened by the recipients matching private key. (Most secure)
• Apply password protection Shared password protection is a simple way to control editing and redistribution (printing and forwarding) of valuable information. (Somewhat secure since passwords can be shared)
• Apply a self signed signature A sender can conveniently create and apply a signature within the program. (limited security, since the signature cannot be validated through a third party)

Rainbow PDF Digital Signature has different ways to add signatures and Signature fields to your document.

There are several ways to set signatures:

• You can create a signature field and set a signature at the same time
• You can create just a signature field to be signed by the recipient
• You can add signature to an already created field
  

For flexibility, there are various permissions settings You can fine tune what the recipient does with the received information (print it, forward it or just sign and return).
