Java encryption algorithm--MD5 encryption and hash hashing with secret key encryption algorithm source code Recently learned encryption algorithm knowledge, using MD5 encryption, Baidu a lot of online data, not very detailed, here on how to implement the MD5

advent of the Internet era, floppy disks are far from meeting people's needs for storing large volumes of information. More and more people are choosing CDs to back up data, in this way, the precious data in the computer can be stored for a longer time. If we burn data on a CD using the traditional method, we can only back up some common data, but it is dangerous to back up some very important data, the information may be illegally obtained by others. Here we will introduce a software named "

The example of this paper describes the Base64 encryption, MD5 encryption and SHA1 encryption implemented by JS. Share to everyone for your reference, specific as follows: 1, Base64 encryption The Base64.js file is introduced into the page, and the method is called: 2, MD5

The RSA algorithm is the first algorithm that can be used for both data encryption and digital signature. It is easy to understand and operate, and is also popular. Its security is based on the difficulty of big integer factorization, while the big integer factorization is a famous mathematical problem. So far, there is no effective solution, therefore, the security of the RSA algorithm can be ensured. The RSA algorithm consists of the generation of

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) During webpage creation (in fact, webpage Trojans), the most worrying thing is
