/**
 * {@module wijmo.pdf.security}
 * Provides PDF encryption and permissions settings for the {@link wijmo.pdf} module.
 *
 * Add this module on page to be able to use the {@link wijmo.pdf.IPdfDocumentOptions.ownerPassword},
 * {@link wijmo.pdf.IPdfDocumentOptions.permissions} and {@link wijmo.pdf.IPdfDocumentOptions.userPassword}
 * properties while creating an instance of the {@link wijmo.pdf.PdfDocument} class:
 *
 * ```typescript
 * import { PdfDocument, saveBlob } from '@mescius/wijmo.pdf';
 * import '@mescius/wijmo.pdf.security';
 *
 * let doc = new PdfDocument({
 *    userPassword: 'abc',
 *    ended: (doc, args) => {
 *       saveBlob(args.blob, 'document.pdf');
 *    }
 * });
 *
 * doc.end();
 * ```
 *
 * This module incorporates modified versions of the
 * <a href="https://github.com/feross/buffer" target="_blank">buffer</a>,
 * <a href="https://github.com/brix/crypto-js" target="_blank">crypto-js</a> and
 * <a href="https://github.com/reklatsmasters/saslprep" target="_blank">saslprep</a>
 * libraries.
