Office software is perfect for security because it's office software, so it's often possible to design company secrets and privacy. Therefore, Microsoft in the development of each version of Office will have the ability to encrypt files, previously mentioned word encryption techniques, we remember. Let me tell you today how to encrypt Excel forms. Many netizens may have already, but in order to help some ju

Encryption | data | Introduction to Algorithms First, a brief introduction to the background of encryption. Because the United States prohibits several cryptographic algorithms from exporting encrypted digits (such as SSL's 40-bit encryption limit), this article describes a simple character encryption algorithm that an ASP can use, rather than a restricted encryption algorithm. In fact, the encryption algorithm introduced here for the general application is enough to decrypt people for a while.

The most reliable way for a Web site to encrypt data in case it is stolen is to encrypt it using a public key encryption algorithm, which is used throughout the transmission and can be implemented for HTTP sites that do not use HTTPS. 　　Function description Because HTTP is the direct transmission of plaintext data, in the increasingly serious network security today, unencrypted HTTP way has become precariou

Encrypt encrypted messages sent externally I have modified the previous GetXmlDocument method so that it can use the X.509 asymmetric encryption technique implemented by WSE. Encrypted response message, the Findcertificatebysubjectstring method can be used to receive a public backup of the client certificate, a client certificate from a personal storage room from the local machine account. This certificate is then used to create a new X.509 security

Transferred from Wang Zhongzhou's personal blogAbout SQLiteSQLite is a lightweight, cross-platform, open-source database engine that has the advantage of read-write efficiency, total consumption, latency, and overall simplicity, making it the best solution for mobile platform databases (such as iOS, Android). However, the free version of SQLite has a fatal disadvantage: encryption is not supported. This results in the data stored in SQLite can be seen by anyone using any text editor. For example

Every time we create a database-driven personalized web site, we must protect user data. Although hackers can steal personal passwords, the more serious problem is that they can steal the entire database and then immediately use all the passwords. Principle A good practice is not to store the actual passwords in the database, but to store their encrypted versions. When we need to authenticate the user, we only need to encrypt the user's password and t

1. MD5 EncryptionIn any formal enterprise application, no plaintext is used in the database to store passwords, and in previous chapters we did not encrypt the user passwords in the database for convenience, which is extremely naïve in practice. You can imagine, as long as someone into the database can see everyone's password, this is a terrible thing, so we must at least encrypt the password, so that even
