标准范围

本文档指定了如何通过向加密字典和拖车字典添加扩展来扩展ISO 32000-2:20 20规范，以为加密的PDF文档提供完整性保护。本文档还确保扩展是完全向后兼容的。这些扩展面向创建PDF文件的软件（PDF编写器）、读取现有PDF文件并（通常）解释其内容以供显示的软件（PDF阅读器）、读取和显示PDF内容并与计算机用户交互以可能修改和保存PDF文件的软件（交互式PDF处理器）以及出于各种其他目的读取和/或写入PDF文件的PDF产品（PDF处理器）的开发人员。笔记？PDF编写器和PDF阅读器是交互式PDF处理器的更专业的分类，两者都是PDF处理器。本文件未指定以下内容:—？将纸质或电子文档转换为PDF文件格式的具体流程；—？渲染的具体技术设计、用户界面实现或操作细节；—？存储这些文档的特定物理方法，例如介质和存储条件；—？用于验证PDF文件或PDF处理器的一致性的方法；—？所需的计算机硬件和/或操作系统。

This document specifies how to extend the ISO 32000-2:2020 specification by adding extensions to the Encrypt dictionary and trailer dictionary to provide integrity protection to the encrypted PDF document. This document also ensures that extensions are fully backward-compatible.

These extensions are intended for developers of software that creates PDF files (PDF writers), software that reads existing PDF files and (usually) interprets their contents for display (PDF readers), software that reads and displays PDF content and interacts with the computer users to possibly modify and save the PDF file (interactive PDF processors) and PDF products that read and/or write PDF files for a variety of other purposes (PDF processors).

NOTE            PDF writers and PDF readers are more specialized classifications of interactive PDF processors and both are PDF processors.

This document does not specify the following:

—     specific processes for converting paper or electronic documents to the PDF file format;

—     specific technical design, user interface implementation, or operational details of rendering;

—     specific physical methods of storing these documents such as media and storage conditions;

—     methods for validating the conformance of PDF files or PDF processors;

—     required computer hardware and/or operating system.
