## PdfEncryptionDetails.user_password property

Specifies the user password required for opening the encrypted PDF document.


```python
@property
def user_password(self) -> str:
    ...

@user_password.setter
def user_password(self, value: str):
    ...

```

### Remarks

The user password will be required to open an encrypted PDF document for viewing. The permissions specified in
[PdfEncryptionDetails.permissions](../permissions/) will be enforced by the reader software.

The user password can be ``None`` or empty string, in this case no password will be required from the user when
opening the PDF document. The user password cannot be the same as the owner password.




### Examples

Shows how to set permissions on a saved PDF document.

```python
doc = aw.Document()
builder = aw.DocumentBuilder(doc=doc)
builder.writeln('Hello world!')
# Extend permissions to allow the editing of annotations.
encryption_details = aw.saving.PdfEncryptionDetails(user_password='password', owner_password='', permissions=aw.saving.PdfPermissions.MODIFY_ANNOTATIONS | aw.saving.PdfPermissions.DOCUMENT_ASSEMBLY)
# Create a "PdfSaveOptions" object that we can pass to the document's "Save" method
# to modify how that method converts the document to .PDF.
save_options = aw.saving.PdfSaveOptions()
# Enable encryption via the "EncryptionDetails" property.
save_options.encryption_details = encryption_details
# When we open this document, we will need to provide the password before accessing its contents.
doc.save(file_name=ARTIFACTS_DIR + 'PdfSaveOptions.EncryptionPermissions.pdf', save_options=save_options)
```
