zip md5

1. The MD5 algorithm is a hash (hash) algorithm (digest algorithm, fingerprint algorithm), not a cryptographic algorithm (error-prone). Any content of any length can be computed with MD5 hash value. MD5 's predecessor: MD2, MD3, MD4. Introduction

What is MD5, what is SHA-1, and how to verify these hashes. There is a single ISO document MD5,SHA-1 interrogation is not the original question, here, to do a final explanation of the above problems. Let's take a look at some basic knowledge about

Based on the features of the MD5 algorithm, we can regard the MD5 encryption process as a function call process. We recommend that you modify it in the following ways to ensure the security of your website users and data to a certain extent: 1.

Just a little bit of encryption is needed in the recent project, and the Java Security Class Library provides a Java.security.MessageDigest class,This messagedigest class provides an application with the functionality of an information digest

PHP compression and decompression class PclZip can be used to compress and decompress Zip files (WinZip and PKZIP). It can process ZIP files, this includes generating compressed files, listing compressed files, and extracting ZIP files. The latest

This occurs when the zip file created under WIN is decompressed in linux, and the Chinese path and file name are garbled, so I wrote a script to convert the file name in the zip file. However, if the zip file is created in the WIN system of Japanese,

First step: Create a Makezip class filePHPclassmakezip{/** * Description: Main method: Generate Compressed Package * @author: MY * @param $dir _path want to compress directory: such as './demo/' * @param $zipName compression After the file name:

As we all know, zip is a compressed file format, MAC OS default supported file format, at that time occasionally when you open the zip file you want to unzip, but automatically become a cpgz file without decompression, and then double-click the Cpgz

For details about how to use php to generate an encrypted zip file, phpmyadmin contains a zip. lib. php file, which can generate a zip file, but cannot be encrypted. The eldest brother knows how to encrypt it? (I am talking about encryption refers

It originated in the zip created under win under Linux decompression, Chinese path and file name will be garbled, so I wrote a script to convert the code inside the zip file name. However, if it is a zip created under the Japanese, Korean, or
