  Initializes an instance of this class.

  Parameters:

  encryptionAlgorithm - A PdfEncryptionAlgorithm value.

  Example:

  Demonstrates how to set permissions on a PDF document generated by Aspose.Words.

  Document doc = new Document(getMyDir() + "Rendering.docx");
  
  PdfSaveOptions saveOptions = new PdfSaveOptions();
  
  // Create encryption details and set owner password
  PdfEncryptionDetails encryptionDetails = new PdfEncryptionDetails("", "password", PdfEncryptionAlgorithm.RC_4_128);
  
  // Start by disallowing all permissions
  encryptionDetails.setPermissions(PdfPermissions.DISALLOW_ALL);
  
  // Extend permissions to allow editing or modifying annotations
  encryptionDetails.setPermissions(PdfPermissions.MODIFY_ANNOTATIONS | PdfPermissions.DOCUMENT_ASSEMBLY);
  saveOptions.setEncryptionDetails(encryptionDetails);
  
  // Render the document to PDF format with the specified permissions
  doc.save(getArtifactsDir() + "Rendering.EncryptionPermissions.pdf", saveOptions);

Property Getters/Setters Detail

• getEncryptionAlgorithm/setEncryptionAlgorithm

  public int getEncryptionAlgorithm() / public void setEncryptionAlgorithm(int value)
  

  Specifies the encryption algorithm to use. The value of the property is PdfEncryptionAlgorithm integer constant.

  Example:

  Demonstrates how to set permissions on a PDF document generated by Aspose.Words.

  Document doc = new Document(getMyDir() + "Rendering.docx");
  
  PdfSaveOptions saveOptions = new PdfSaveOptions();
  
  // Create encryption details and set owner password
  PdfEncryptionDetails encryptionDetails = new PdfEncryptionDetails("", "password", PdfEncryptionAlgorithm.RC_4_128);
  
  // Start by disallowing all permissions
  encryptionDetails.setPermissions(PdfPermissions.DISALLOW_ALL);

  // Start by disallowing all permissions
  encryptionDetails.setPermissions(PdfPermissions.DISALLOW_ALL);
  
  // Extend permissions to allow editing or modifying annotations
  encryptionDetails.setPermissions(PdfPermissions.MODIFY_ANNOTATIONS | PdfPermissions.DOCUMENT_ASSEMBLY);
  saveOptions.setEncryptionDetails(encryptionDetails);
  
  // Render the document to PDF format with the specified permissions
  doc.save(getArtifactsDir() + "Rendering.EncryptionPermissions.pdf", saveOptions);

• getPermissions/setPermissions

  public int getPermissions() / public void setPermissions(int value)
  

  Specifies the operations that are allowed to a user on an encrypted PDF document. The default value is PdfPermissions.DISALLOW_ALL. The value of the property is PdfPermissions integer constant.

  Example:

  Demonstrates how to set permissions on a PDF document generated by Aspose.Words.

  Document doc = new Document(getMyDir() + "Rendering.docx");
  
  PdfSaveOptions saveOptions = new PdfSaveOptions();
  
  // Create encryption details and set owner password
  PdfEncryptionDetails encryptionDetails = new PdfEncryptionDetails("", "password", PdfEncryptionAlgorithm.RC_4_128);
  
  // Start by disallowing all permissions
  encryptionDetails.setPermissions(PdfPermissions.DISALLOW_ALL);
  
  // Extend permissions to allow editing or modifying annotations
  encryptionDetails.setPermissions(PdfPermissions.MODIFY_ANNOTATIONS | PdfPermissions.DOCUMENT_ASSEMBLY);
  saveOptions.setEncryptionDetails(encryptionDetails);
  
  // Render the document to PDF format with the specified permissions
  doc.save(getArtifactsDir() + "Rendering.EncryptionPermissions.pdf", saveOptions);

  Document doc = new Document(getMyDir() + "Rendering.docx");
  
  PdfSaveOptions saveOptions = new PdfSaveOptions();
  
  // Create encryption details and set owner password
  PdfEncryptionDetails encryptionDetails = new PdfEncryptionDetails("", "password", PdfEncryptionAlgorithm.RC_4_128);
  
  // Start by disallowing all permissions
  encryptionDetails.setPermissions(PdfPermissions.DISALLOW_ALL);
  
  // Extend permissions to allow editing or modifying annotations
  encryptionDetails.setPermissions(PdfPermissions.MODIFY_ANNOTATIONS | PdfPermissions.DOCUMENT_ASSEMBLY);
  saveOptions.setEncryptionDetails(encryptionDetails);
