Topic: What security handlers come with Adobe Reader 7?

Does anyone know what security handlers come built-in into Adobe Reader 7?

The PDF Reference v1.6 says:
Public-key security handlers use the industry standard Public Key Cryptographic
Standard Number 7 (PKCS#7) binary encoding syntax to encode recipient list,
decryption key, and access permission information.
The Filter entry is the name of a public-key security handler. Examples of existing
security handlers that support public-key encryption are Entrust.PPKEF,
Adobe.PPKLite, and Adobe.PubSec. This handler will be the preferred handler
when encrypting the document.

After reading this, one assumes that Acrobat Reader has Entrust.PPKEF, Adobe.PPKLite, and Adobe.PubSec handlers built-in.

My problem is that I could not verify these assumptions (in some official Reader manual/reference/specification), or find a more complete list of built-in handlers.

Does anyone has more information about this?
Information about handlers built-in into versions 4, 5 and 6 of Acrobat Reader would also be useful.
