PDF file is not encrypted

[pallavinishanth]

Describe the bug
I am not able to password protect the pdf file, I just want owner password protected.

Here is the sample snippet of code that I wrote to password protect existing pdf file.

PDFBoxResourceLoader.init(context);
AccessPermission permission = new AccessPermission();
permission.setCanExtractContent(false);
permission.setCanModify(false);
permission.setCanModifyAnnotations(false);
permission.setCanPrint(true);
permission.setReadOnly();
StandardProtectionPolicy spp = new StandardProtectionPolicy("password" , "" , permission);
spp.setEncryptionKeyLength(128);
spp.setPermissions(permission);
BouncyCastleProvider provider = new BouncyCastleProvider();
Security.addProvider(provider);
try {
PDDocument pdfDoc = PDDocument.load(pdfFile);
pdfDoc.protect(spp);
pdfDoc.save(pdfFile);
pdfDoc.close();
} catch (IOException e) {
Log.e(Nimbus.TAG, "Exception while loading pdf file ", e);
}

Not sure why the pdf is not getting encrypted, let me know if anything is wrong in the above code snippet. Any help is much appreciated.

Environment details:

• PdfBox-Android version: [e.g. 2.0.27.0]
• Android API version: [e.g. API 33]
