Networks initially adopted the WEP (Wired Equivalent private) security mechanism, but later found that WEP was insecure. 802.11 organizations began to develop new security standards, that is, the later 802.11i protocol. However, it takes a long time for the establishment of standards to the final release, and considering that consumers will not give up their original wireless devices for the sake of network security, before the launch of the Wi-Fi Alliance standard, based on the draft 802.11i,

pay great attention to the security of your network, do not use WEP as much as possible in the future, because it is really not very secure.

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.
Symmetric encryption

Encryption for wireless routers ensures the security of our wireless networks, especially for hackers who steal accounts and network users. Many users who use wireless routers do not know how to encrypt their routes. It is very important to set a password, today, JCG smart wireless is here to share with you the main encryption methods and methods of wireless routers.I. wireless
WPA2: more powerful wireless encryption technology
It may take some time for the full IEEE 802.11i standard to be launched, and the Wi-Fi Alliance wants to enable the new security standard to be deployed as soon as possible to eliminate users'Wireless NetworkSecurity concerns allow the wireless network market to expand quickly. Therefore, the draft of the fifth draft of the IEEE 802.11i (IEEE 802.11i draft 3) of TKIP is developed as a benchmark.WPA. A

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)
