;!! In order to use the following WinBatch code, you have to agree with the licensing rules of "PDFlib GmbH"
;!! and download the file "PSP-1.0.1.msi.zip" from their website "http://www.pdflib.com".
;------------------------------------------------------------------------------------------------------------------------------------------
; This WinBatch implementation is based on PDFlib PSP Version 1.0.1 and manual from October 22, 2002.
;------------------------------------------------------------------------------------------------------------------------------------------
; From the PSP manual:
; Applying the PSP License Key
; All versions of the PSP command-line tool and programming library can be used as fully
; functional evaluation versions regardless of whether or not you obtained a commercial license.
; However, unlicensed versions will only allow the use of passwords which we consider not secure enough
; for professional applications (see Section 1.2, »Strength of PDF Encryption« for more details):
; passwords with 5 characters or less can be applied with the free evaluation version of PSP.
; However, even if you use only short passwords, unlicensed versions of PSP must not be used for production purposes,
; but only for evaluating the product’s features and performance.
; Using PSP for production purposes or applying passwords with more than 5 characters requires a valid PDFlib PSP license key.
;------------------------------------------------------------------------------------------------------------------------------------------
; Windows users can enter the license key when they install PSP using the supplied installer.
; This is the recommended method on Windows.
; If you do not have write access to the registry or cannot use the installer refer to the following method:
; Apply the license key manually each runtime by writing it directly into the script (or read it from an inifile):
; oPSP.set_parameter ("license", "...your license key...")
;------------------------------------------------------------------------------------------------------------------------------------------
; Perhaps after this Demo you will like PSP so much for your PDF files, so rent a license from "PDFlib GmbH".
; ... and now ... Happy WinBatching and private PDF Securing for free!

;
; Q: What can you do with "PDFlib - PSP (Pretty Safe PDF)"?
; A: PSP does Securing of PDF Documents.
;
; PSP applies or removes Acrobat standard security features to PDF files.
; PSP can apply user and master passwords, and set access permissions to prevent
; printing the document with Acrobat, extracting text, modifying the document, etc.
; PSP uses 40-bit or 128-bit encryption keys.
; 128-bit keys have been introduced in Acrobat 5, and are also known as "secure" keys.
;
; With PDFlib PSP you can do the following:
; - Encrypt a PDF document with a user or master password (or both).
; - Remove PDF encryption if you know the document’s master password.
; - Add or remove permission settings (e.g., printing or text extraction not allowed)
; if you know the document’s master password.
; - Query information about the security status (encrypted with user or master password),
; encryption scheme (Acrobat standard security, WebBuy, etc.), permission settings,
; and document info fields.
; - Combine PSP with our PDFlib 4 product for generating encrypted PDF documents dynamically.
;
;
; Q: Is PSP a command-line tool or a PSP library?
; A: PSP is available both as a programming library (component) for various development languages,
; and as a command-line tool for batch operations.
; Both offer the same security features, but are suitable for different deployment tasks.
;
; Note: The PSP command-line tool can be used as fully functional evaluation version regardless
; of whether or not you obtained a commercial license. However, unlicensed versions will only
; allow the use of passwords which we consider not secure enough for professional applications
; (see Manual, Section 1.2, "Strength of PDF Encryption" for more details):
; Passwords with 5 characters or less can be applied with the free evaluation version of PSP.
; However, even if you use only short passwords, unlicensed versions of PSP must not be used
; for production purposes, but only for evaluating the product’s features and performance.
; Using PSP for production purposes or applying passwords with more than 5 characters
; requires a valid PDFlib PSP license key.
;
;
; Q: Is it possible to set Passwords with PSP into PDF files?
; A: Yes. It is strongly recommended to have a closer look into the developer's "PSP-manual.pdf"!
;
;
; Q: Is it possible to set Permissions with PSP into PDF files, e.g. forbid printing?
; A: Yes. It is strongly recommended to have a closer look into the developer's "PSP-manual.pdf"!

; If the document is encrypted and info entries will be queried,

; an empty password may be supplied.
; If the document is encrypted and info entries will be queried,
; the user password must be supplied.
; Otherwise the document’s master password is required.
;
; hMemBuffer The memory-based method is faster, but requires more memory.
; It is recommended for dynamic PDF generation and encryption in Web application
; unless you deal with very large documents.
; Instead of generating a PDF file on disk with PDFlib 4, use in-core PDF generation
; (by supplying an empty file name to PDF_open_file()), fetch the contents of the buffer
; containing the generated PDF data using PDF_get_buffer(), and pass this buffer
; to PSP using PSP_open_mem( ). Note that it is not possible to fetch the PDFlib 4 buffer
; contents in multiple portions since the full document must be supplied to PSP in a single
; buffer. Therefore you must call the PDF_get_buffer() method between PDF_close()
; and PDF_delete().

;
; sPasswordMaster ....... The master password for the document. If this is an empty string no master password will be applied.

; sAccess ....... A string with the access permissions for the output document.
; It contains any number of the noprint, nomodify, nocopy, noannots, noforms, noaccessible, and nohiresprint
; keywords, separated from each other by a colon character ’:’.
; iEncryptAlgorithm ..... A number which identifies the algorithm used for PDF encryption:
; 0 ... means no encryption.
; This can only be used if no user and master password and no access restrictions have been specified.
; 1 ... is the standard algorithm used in PDF 1.1 - 1.3 (up to Acrobat 4), and can be used with 40-bit keys.
; The PDF version of the input document will be preserved.
; 2 ... is the standard algorithm used in PDF 1.4 (Acrobat 5), and can be used with 128-bit keys.
; The PDF version of the output document will be pushed to PDF 1.4 if necessary.
; iEncryptKeyLength ..... The length of the encryption key in bits.
; The standard key length in Acrobat 4 is 40 bits. Standard: 40-bit RC4 (Acrobat 3.x, 4.x)
; In Acrobat 5 it is 128 bits.
; Algorithm 0 (no encryption) requires a key length of 0 bits.
; sFilename ............. The name of the generated output file, which should be different from the input file name
; supplied to PSP_open_file(). If this is an empty string the output will be generated in memory,
; and can later be fetched with PSP_get_buffer().
