public boolean encryptFile(String userPassword, String ownerPassword, DocumentPrivilege privilege, int keySize)
Encrypts Pdf file with userpassword and ownerpassword and sets the document's privileges to access. The user password and the owner password can be null or empty. The owner password will be replaced with a random string if the input owner password is null or empty.
String inFile = "..\\AsposePdfKitExample\\example1.pdf"; // The TestPath may be // re-assigned. String outFile = "..\\AsposePdfKitExample\\Kit0401.pdf"; // The TestPath may be // re-assigned.

encryption and KeySize.x256 for 256 bits encryption.public boolean encryptFile(String userPassword, String ownerPassword, DocumentPrivilege privilege, int keySize, int cipher)
Encrypts Pdf file with userpassword and ownerpassword and sets the document's privileges to access. The user password and the owner password can be null or empty. The owner password will be replaced with a random string if the input owner password is null or empty. There are 6 possible combinations of KeySize and Algorithm values. However (KeySize.x40, Algorithm.AES) and (KeySize.x256, Algorithm.RC4) are invalid and corresponding exception will be raised if kit encounters this combination.
