PDF security handler registration: must I use "Standard"?

For this API:

PDDocSetNewCryptHandler(document, ASAtomFromString("Standard"));

The API Reference says:

newCryptHandler - The ASAtom for the name of the new security handler to use for the document. This name must be the same as the pdfName used when the security handler was registered using PDRegisterCryptHandler().

Do I have to use "Standard"?

Answer
"Standard" security handler is what APDFL uses.

There are other handlers available, such as these:

• LiveCycle Management
• Public and Private keys
• Digital Rights Management
• Plug-ins

But these other handlers are not set up to work with the Adobe PDF Library without the user having to do a substantial amount of coding.
