message digest 5

Previous wordsThe basic certification described in the previous article is convenient and flexible, but extremely unsafe. The user name and password are transmitted in clear text, and no action is taken to prevent tampering with the message. The

No authentication method After a correct client request is sent to the server, the HTTP server returns the 200 status code and directly returns the content. Message example: Request: Get. http: // 10.127.194.3: 8061/voiceobjects ..... Return

Information digest encryption MD2, MD4, MD5, md2md4 The confidentiality of user data has always been a headache for Internet companies. How can we prevent the disclosure of users' personal information? Today we will introduce you to the information

Chapter 3 message digest algorithm-MD5, digest-md5 Note: In this section, refer to "verify data integrity-message digest algorithm" in Chapter 2nd of Java encryption and decryption art (version 6th" 3.1 message digest algorithm: prevents tampering

Basic authentication is convenient and flexible, but extremely unsafe. The user name and password are transmitted in clear text, and no action is taken to prevent tampering with the message. The only way to safely use Basic authentication is to use

First, briefMAC (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 adds a key on this basis. So Mac algorithms are often

SHA and sha of message digest algorithm for Information Encryption SHA is an implementation method of the message digest algorithm. The implementation of MD2 \ 4 \ 5 has been summarized earlier. Next, we will summarize the implementation of SHA. Jdk

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 adds a key on this basis. So Mac algorithms are often called HMAC

Http authentication .... BASIC:In the context of an HTTP transaction, Basic access authentication are a method for a Web browser or other client Program to provide a user name and password when making a request. [1]Before transmission, the user name
