DotNet encryption-symmetric encryption and dotnet encryption -- Just one day before the Chinese New Year's Eve, it's close to you to go home. Some people are excited, because they will have to go through the annual installation drama in a few days, and all the parties, including relatives, friends, and students, will show off, therefore, I have to pay a year-end

PHP, and phpdes. PHP encryption and decryption functions and DES encryption and decryption instances. phpdes encryption and decryption instances this article describes the application of the encryption and decryption functions in PHP and DES encryption and decryption. PHP

can no longer have actual control. Or, if your windows system is infected by a Trojan with a record key, enter a credit card in the SSL session of the browser R to prevent theft. Endurer Note: 1. Close to, near The general belief of SSL providing security is precisely why limit of the newer phishing scams that use SSL are tricking people into giving up personal information. SSL does not provide more than simple data transmission security. the real question is: what happens to the data afterward

Symmetric encryption and asymmetric encryption, asymmetric encryption What is encryption? Encryption is divided into two parts: algorithm and key. The algorithm remains unchanged, and the key changes. For more information, see the following example. Key: abcedfgh-> 12345678.

[Preface]This article briefly introduces the concepts related to encryption technology, and finally summarizes the existing encryption technology in java as well as its usage and examples. [Simple encryption] 1. Simple concept Plaintext: the information before encryption Ciphertext: Confidential Information Algorithm

This article mainly introduces the base64 encryption, md5 encryption and sha1 encryption methods implemented by JS, and analyzes in detail various common JavaScript encryption methods and implementation techniques based on the example form, if you need it, refer to the example in this article to describe the base64

One, asymmetric encryptionAsymmetric encryption has a set of key pairs, one is public, anyone can obtain, called the public key;One is self-preservation and strictly confidential, called the private key.The rules are as follows:by someone A the public key encrypted message, only by the A the private key is decrypted;by A The private key encrypts the message, only by the A decryption of the public key. sender, the receiver holds the public key / privat

For security reasons, we typically choose an encryption method to encrypt text that requires security, while BASE64 encryption and DES64 encryption are common cryptographic algorithms. I remember what I used in the previous project was the combination of these two cryptographic algorithms: Base64 + des encryption. Of c

This document describes seven methods: I. Simplest encryption and decryption Ii. Use the Escape Character "\" 3. Use the script encoder produced by Microsoft for encoding (simple decoding) 4. Add any NUL null characters (hexadecimal 00 h) (self-created) 5. Useless content and line feed space tab Method Vi. Self-write decryption Function Method 7. Misuse (self-developed) During webpage creation (in fact, webpage Trojans), the most worrying thing is

encryption technologies: symmetric encryption (private key encryption), asymmetric encryption (public key encryption), and individual encryption. Symmetric encryption: symmetric

Symmetric encryption and asymmetric encryption, asymmetric encryptionSafe communication methods must meet the following three conditions:1. Integrity, that is, the message has not been tampered with midway through.2. Confidentiality, which cannot be decrypted by a third party.3. verifiable. The message receiver can determine who sent the message. Symmetric encryption
