With the development of symmetric cipher, the DES data Encryption Standard algorithm, because of its small key length (56 bits), has not adapted to the requirements of today's distributed open Network for data encryption security, so 1997 NIST

First, the basic concept of AES algorithm AES is the abbreviation of Advanced Encryption Standard (Advanced encryption Standard), AES has the following three characteristics. 1 AES is symmetric encryption algorithm The concept of symmetric

Recently I used to encrypt text content, so I checked the common encryption algorithms: Des (Data Encryption Standard): symmetric algorithm, Data Encryption Standard, fast, suitable for encrypting a large amount of data;3DES (Triple DES): It is a

Today in the Android project using AES to decrypt the data, encountered a lot of problems, the Internet also found a lot of information, also not. But finally let me get out, here to record this, do not let others go my detour, because most of the

Recently used to encrypt the text content, and then looked at the usual encryption algorithm:DES (Data Encryption Standard): symmetric algorithm, data encryption standards, fast, suitable for encrypting large amounts of data;3DES (Triple des): is

The development project needs to cache important data locally so that it is read offline, and if the data is not processed, it can easily cause loss. Therefore, we generally encrypt this kind of data. Here, we mainly introduce two kinds of simple

Android security encryption feature article index Android Secure encryption: Symmetric encryption Android Secure encryption: Asymmetric encryption Android Secure encryption: Message digest Digest Android Security Encryption:

This example describes the AES encryption method in Java. Share to everyone for your reference. Specifically as follows: Java code: keygenerator kg = keygenerator.getinstance ("AES"); Gets the key generator kg.init (256);// //des algorithm
