Using tar and direct file system exchange 使用tar和直接文件系统(DFS)交换
At first, this paper briefly introduces the foundational knowledge of cryptography. Then emphasizes the principle and implementation of two file encryption systems ( virtual disk encryption system and direct file encryption system ). 首先简要介绍了密码学的基础知识,然后重点介绍两种文件加密系统(虚拟磁盘加密系统、直接文件加密统)的基本原理和实现方法。
The direct file encryption system is realized based on OPENSSL including three major modules : user interface module, interface module, base encryption module. 直接文件加密系统是基于OPENSSL实现的,也有三大模块:用户界面模块、接口模块、底层模块。
Because versioning involves the entire document, it is typically implemented by direct use of the file system. 因为历史版本涉及整个文档,所以它通常直接通过文件系统来实现。
If you want to create a.tar file and use this, rather than performing the direct copy, you must have a file system capable of holding all the files from your source directory. 如果您需要创建一个.tar文件并使用这种方法,而不是执行直接的复制,那么您必须拥有一个能够容纳源目录中所有文件的文件系统。
