Source author Wang HuiChapter 4 Basic Knowledge 1.1. Single-key password systemThe single-key cryptography system is a traditional encryption algorithm, which means that the sender and receiver of the information use the same key for encryption and

Come from:http://blog.csdn.net/lonelyroamer/article/details/7630594 I. Overview The MAC algorithm combines the advantages of the MD5 and Sha algorithms and joins the key support, which is a more secure message digest algorithm. MAC (Message

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

Previous wordsCryptographic modules provide a way to encapsulate security credentials during an HTTP or HTTPS connection. It also provides encapsulation of OpenSSL's hash, HMAC, encryption (cipher), decryption (decipher), signature (sign), and

In general, the encryption algorithm used is relatively simple and efficient, key short, encryption and decryption speed, deciphering extremely difficult. This paper introduces the use of Md5/sha1,dsa,desede/des,diffie-hellman. 1th Chapter Basic

In the development of various application systems, often need to store user information, many places have to store user passwords, and the user password directly stored in the server is obviously unsafe, this article briefly introduces the work of

1 sha Encryption: Secure Hash algorithm is mainly applicable to digital signature algorithms (Digital Signature algorithm DSA) defined in the digital signature standard (Digital Signature Standard DSS). For messages that are less than 2^64 bits in

MAC (Message authentication code, messaging authentication Code algorithm) is a key hash function algorithm that is compatible with the features of the MD and SHA algorithms, and the key is added on this basis. Therefore, the Mac is also called an
