There are different encryption type as given below.
ITEXT7 PDFWRITER PDF
We can set different type of permissions to PDF
ITEXT7 PDFWRITER PASSWORD
To add password to a new PDF, we need to use tEncryption() method. tEncryption(byte userPassword, byte ownerPassword, int permissions, int encryptionType) To encrypt existing PDF with password, iText provides tEncryption which accepts same arguments as tEncryption. While creating password protected PDF, we need to add user password, owner password, permission and encryption type. tEncryption() method is used to add password to new PDF.
