for programmers interested in including the LPS security mechanism within their products without the
encrypted, 'stand-alone' nature of a 'document' (C/C++ and Visual Basic 6.0)
The consumer of an LPS protected document must be in
possession of the document and know two items:
1. the document owner name, and
2. the password which is activated for the specific date and/or time of day.
A document is protected from unauthorized use by the document owner,
producer, or distributor using a special encoding program (lpsMake.exe). A primary
security mechanism is the document owner name. Without knowledge of
this public encryption key , the document is not useful
to anyone. Therefore, its selection and spelling requires careful
consideration.
