This article mainly shares with you an article about PHP switching between bin2hex and hex2bin through AES encryption/decryption. It has a good reference value and I hope it will be helpful to everyone. Let’s follow the editor and take a look.
<?php /** * 通过AES加密请求数据 * * @param array $query * @return string */ function AESEncryptRequest($encryptKey, $query){ return $this->encrypt_pass($query,$encryptKey); } // 加密 function encrypt_pass($input, $key) { $size = mcrypt_get_block_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_ECB); $input = pkcs5_pad($input, $size); $td = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_ECB, ''); $iv = '0102030405060708'; mcrypt_generic_init($td, $key, $iv); $data = mcrypt_generic($td, $input); mcrypt_generic_deinit($td); mcrypt_module_close($td); $data = bin2hex($data); return $data; } //填充 function pkcs5_pad ($text, $blocksize) { $pad = $blocksize - (strlen($text) % $blocksize); return $text . str_repeat(chr($pad), $pad); } /** * 通过AES解密请求数据 * * @param array $query * @return string */ function AESDecryptResponse($encryptKey,$data){ return $this->decrypt_pass($data,$encryptKey); } // 解密 function decrypt_pass($sStr, $sKey) { $iv = '0102030405060708'; $decrypted= mcrypt_decrypt( MCRYPT_RIJNDAEL_128, $sKey, hex2bin($sStr), MCRYPT_MODE_ECB, $iv ); $dec_s = strlen($decrypted); $padding = ord($decrypted[$dec_s-1]); $decrypted = substr($decrypted, 0, -$padding); return $decrypted; }
