message digest algorithm example

Java Cryptographic Decryption Message digest algorithm (MD5 SHA MAC)Message digestMessage Digest, also known as a Digital digest (digitally Digest).It is the only fixed-length value corresponding to a message or text that is generated by a one-way

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

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

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

Digest access authenticationHttps://en.wikipedia.org/wiki/Digest_access_authentication Digest access authentication is one of the Agreed-upon methods a Web server can use to negotiate credentials, suc H as username or password, with a user '

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
