Public Enum to define PDF encryption algorithm types.

// Load an existing PDF document
let document: PdfDocument = new PdfDocument(data, password);
// Create security options with AES-128 encryption
let securityOptions: PdfSecurityOptions = {
    encryptionType: PdfEncryptionType.aesBit128,
    userPassword: 'user123'
};
// Apply security settings
document.setSecurity(securityOptions);
// Save the document
document.save('output.pdf');
// Destroy the document
document.destroy();
