The feedback from some customers in the past:

Another simple fact you might want to mention in your documentation (not caused by your program but related).

The passwords must not contain characters such as: % > < | otherwise MS-DOS will treat them as special characters and the password your program receives is different form the original one.

encryptpdf .... -u abc%1def

%1 is treated by MS-DOS like a batch file parameter and gets changed!

When you run encryptpdf.exe Command Line to encrypt your PDF files, you can't use special characters as password, please notice this matter.
