Atitit aes 加密法php实现

<?php

$data="aaaaccc";

$secret_key="abcdefgh";

//echo openssl_encrypt($data, $this->method, $this->secret_key, $this->options, $this->iv);

echo openssl_encrypt($data, 'AES-128-ECB', $secret_key,0, "");

echo "\r\n";

echo openssl_decrypt("qjuIItb9e3IuYk0hi8ZN4g==", 'AES-128-ECB', $secret_key,0, "");

• 常见的填充模式有： pkcs5、pkcs7、iso10126、ansix923、zero。
• 加密模式有：DES-ECB、DES-CBC、DES-CTR、DES-OFB、DES-CFB。

常见参数$iv 加解密的向量，有些方法需要设置比如CBC

$method 加密方式

switch($this->bit) {

case 192:$this->cipher = MCRYPT_RIJNDAEL_192; break;

case 256:$this->cipher = MCRYPT_RIJNDAEL_256; break;

default: $this->cipher = MCRYPT_RIJNDAEL_128;

}

switch($this->mode) {

case 'ecb':$this->mode = MCRYPT_MODE_ECB; break;

case 'cfb':$this->mode = MCRYPT_MODE_CFB; break;

case 'ofb':$this->mode = MCRYPT_MODE_OFB; break;

case 'nofb':$this->mode = MCRYPT_MODE_NOFB; break;

case 'cbc':$this->mode = MCRYPT_MODE_CBC; break;

default: $this->mode = MCRYPT_MODE_CBC;

$options 数据格式选项（可选）【选项有：】

• 0
• OPENSSL_RAW_DATA=1
• OPENSSL_ZERO_PADDING=2
• OPENSSL_NO_PADDING=3

需要注意：如果$method为DES-ECB，则$iv无需填写
