The following Java code example removes password-based
encryption from a PDF document named EncryptLoan.pdf. The
master password value used to remove password-based encryption is PermissionPassword.
The unsecured PDF document is saved as a PDF file named noEncryptionLoan.pdf.
(See Removing Password Encryption.)
