Class Summary

Class	Description
PdfEncryptor	Encrypts an in-memory COSDocument for output, using the PDF Standard security handler -- the write-side counterpart of StandardSecurityHandler (a reader, which deliberately doesn't expose a forward/encrypting direction).
PdfEncryptor.Options
StandardSecurityHandler	Implements the PDF Standard security handler (ISO 32000-1 §7.6.3 / ISO 32000-2 §7.6.4): given a document's /Encrypt dictionary, its first /ID element, and a candidate password, derives the file encryption key and can then decrypt any string or stream belonging to an indirect object in that document.
