the Java classes involved in DES encryption decryption Cipher This class provides password functionality for encryption and decryption. It forms the core of the Java cryptographic Extension (JCE) framework .To create the Cipher object, the application invokes the Cipher getinstance method and passes the name of the requested transformation to it. You can also s

, replacement, and shift operations.3DES A common variant of DES is threefold des, a mechanism that uses a 168-bit key to encrypt data three times; it generally (but not always) provides extremely powerful security. If the three 56-bit sub-elements are the same, the Triple DES is backward compatible with DES.Features

Label:Des_decrypt (Crypt_str[,key_str])Use Des_encrypt () to encrypt a string. If an error occurs, this function returns NULL.Note that this function will only work if MySQL is configured with SSL support. See section 5.8, 7, "Using a secure connection".Without a given key_str parameter, Des_decrypt () first checks the first byte of the encrypted string to determine the number of DES cipher keys used to encrypt the original string, and then reads the

Recently, there is a new project to do with Java, the old project is ASP, interface transmission needs des plus decryption, online search of some information, most can not be used, after debugging and processing, the specific code is as follows:The key must be 8 bits. The corresponding Java method is as follows:Package com.testspring;Import Javax.crypto.Cipher;Import Javax.crypto.SecretKey;Import Jav

As a web front-end application, communication with the server or back-end communication, as well as the transfer of data between different users, in some specific cases need to encrypt some information transmission, in an event to remove information and decryption, get the correct information. Looking at different languages and different algorithms, there are many options. Today, from the most basic encryption and decryption algorithm

Based on the analysis in the previous article "Introduction to Real Data Encryption Using DES (analysis)", Java can be used to encrypt strings, however, the legacy problem is that the string cannot be decrypted, because after the encrypted byte array is converted into a string, it will be different from the original byte array, and there will be fewer digits, I don't know why. Isn't a one-to-one conversion
