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

AES encryption is a very advanced encryption. many people say it is very difficult to crack AES encryption. the following section describes an example of how to use the AES encryption algorithm to encrypt data. when studying Discuz, we found that

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

Advanced Encryption Standard (English: Advanced encryption Standard, abbreviation: AES), also known as the Rijndael encryption method in cryptography, is a block encryption standard used by the U.S. federal government. This standard, which replaces

With the development of symmetric passwords, The des Data Encryption Standard algorithm has a small key length (56 bits) and is no longer applicable to the requirements of distributed open networks for data encryption security, therefore, in 1997,

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

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 codeThe Code is as follows:Require_once ('./AES. php ');// $ Aes = new AES ();$ Aes = new AES (true); // stores encrypted strings in hexadecimal format.// $ Aes = new AES (true, true); // The encrypted string is stored in
