First, prefaceWith the broadcast technology hot, all the Live app, the early live app's various request protocol parameter information did not do any encryption measures, but slowly someone began to use the back door began to brush powder attention tool, you can make a new small Hua Dan minute into the net red. So somewhere in this problem, the live app starts encrypting the network request parameters. So that is the focus of this article analysis. Th
Android DES encryption related implementation, a simple implementation of a moment, today to sum up:
DES encryption Introduction:des is a symmetric encryption algorithm, the so-called symmetric encryption algorithm is: Encryption and decryption using the same key algorithm.
There are many encryption functions in php functions, one of which can implement data encryption functions is called the crypt () function. The crypt () function uses a one-way algorithm without corresponding decryption functions. It returns a string encrypted using the DES, Blowfish, or MD5 algorithm. There are a lot of encr
There are several types of encryption in PHP:1. MD5 Encryptionstring MD5 string $str $raw _output false ] )ParametersSTR--the original string.Raw_output--If the optional raw_output is set to TRUE, then the MD5 Digest is returned in the original binary format of 16 bytes in length.This is a non-reversible encryption, execute the following code$password = ' 123456 '; Echo MD5 ($password);Get the result is e10
extension is Java Cryptography Extension (JCE. It is Sun's encryption service software, which includes encryption and key generation functions. JCE is an extension of JCA (Java Cryptography Architecture.
JCE does not specify a specific encryption algorithm, but provides a framework. The specific implementation of the encrypt

Objective:
In addition to landing in the project, payment and other interfaces using RSA asymmetric encryption, outside the use of AES symmetric encryption, today we come to understand the AES encryption.
Several other encryption methods:RSA encryption of Android data encr
