Aspose::Pdf::Facades::PdfFileSecurity::MfEncryptFile method
PdfFileSecurity::MfEncryptFile(System::String, System::String, System::SharedPtr<DocumentPrivilege>, KeySize) method
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. Throws exception if process failed.
bool Aspose::Pdf::Facades::PdfFileSecurity::MfEncryptFile(System::String userPassword, System::String ownerPassword, System::SharedPtr<DocumentPrivilege> privilege, KeySize keySize)
| Parameter | Type | Description |
|---|---|---|
| userPassword | System::String | User password. |
| ownerPassword | System::String | Owner password. |
| privilege | System::SharedPtr<DocumentPrivilege> | Set privilege. |
| keySize | KeySize | KeySize.x40 for 40 bits encryption, KeySize.x128 for 128 bits encryption and KeySize.x256 for 256 bits encryption. |
ReturnValue
True for success.

PdfFileSecurity::MfEncryptFile(System::String, System::String, System::SharedPtr<DocumentPrivilege>, KeySize, Algorithm) method
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. Throws an exception if process failed.

| Parameter | Type | Description |
|---|---|---|
| userPassword | System::String | User password. |
| ownerPassword | System::String | Owner password. |
| privilege | System::SharedPtr<DocumentPrivilege> | Set privilege. |
| keySize | KeySize | KeySize.x40 for 40 bits encryption, KeySize.x128 for 128 bits encryption and KeySize.x256 for 256 bits encryption. |
| cipher | Algorithm | Algorithm.AES to encrypt using AES algorithm or Algorithm.RC4 for RC4 encryption. |
ReturnValue
True for success.
