The Golang standard library for AES encryption is very concise, if not a certain basic knowledge of cryptography, it is easy to confuse.This article provides a
OpenSSL symmetric encryption algorithm commands
1. symmetric encryption algorithm Overview
The openssl Encryption Algorithm Library provides a wide range of symmetric encryption algorithms. We can use the symmetric encryption algorithm commands
Example of AES encryption and decryption in php. AesDemo. php: for example, copy the code as follows :? Phprequire_once (. AES. php); $ aesnewAES (true); store the encrypted string in hexadecimal format. aesDemo. php:
Example,
The code is as
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
Put the code first. There are two files: AES. php (aes algorithm file) and aesDemo. php (application instance file) aesDemo. php:
Example,
The Code is as follows:
Require_once ('./AES. php ');// $ Aes = new AES ();$ Aes = new AES (true); //
aesdemo.php:
Example
Copy the Code code as follows:
Require_once ('./aes.php ');$aes = new Aes ();$aes = new Aes (TRUE);//Store the encrypted string as hexadecimal$aes = new Aes (true,true);//With debug information and encrypted string stored in
