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
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.

When it comes to encryption, it's reminiscent of digital signatures, what are the two often confusing concepts?Encryption: Encryption is a way to send information in a password. Only the person with the correct key can unlock the password for this message. For others, the message looks like a series of random letters, numbers, and symbols.
When it comes to encryption, a digital signature is associated with two concepts that are often confused.
Encryption: Encryption is a way to send information in a password way. Only the person with the correct key can unlock the password for this information. For other people, this information looks like a series of random letters, numbers, and symbols.

Encrypted decryption function and DES encryption and decryption instance in PHP, Phpdes encryption and decryption instance
In this paper, the application of cryptographic decryption function and DES encryption and decryption in PHP is described, and it is shared for everyone's reference. Specific as follows:

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
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.

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
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)
