# Creating password-protected PDFs on Android

A PDF document can be encrypted to protect its contents from unauthorized access.

### KOTLIN

```kotlin

val task = PdfProcessorTask.fromDocument(document)

// Create default document save options.
var documentSaveOptions = document.getDefaultDocumentSaveOptions()
// This will create an encrypted password-protected document.
documentSaveOptions.password = "password"

// Use created save options when processing the document.
PdfProcessor.processDocumentAsync(task, outputFile, documentSaveOptions)

```

### JAVA

```java

final PdfProcessorTask task = PdfProcessorTask.fromDocument(document);

// Create default document save options.
DocumentSaveOptions documentSaveOptions = document.getDefaultDocumentSaveOptions();
// This will create an encrypted password-protected document.
documentSaveOptions.setPassword("password");

// Use created save options when processing the document.
PdfProcessor.processDocumentAsync(task, outputFile, documentSaveOptions);
