php5模式
https://github.com/gunnzhao/AES-CBC-PKCS7Padding-/blob/master/AesCrypter.php
public function encrypt($orig_data) { ???????$encrypter = mcrypt_module_open($this->algorithm, ‘‘, ???????????$this->mode, ‘‘); ???????$orig_data = $this->pkcs7padding( ???????????$orig_data, mcrypt_enc_get_block_size($encrypter) ???????); ???????mcrypt_generic_init($encrypter, $this->key, substr($this->key, 0, 16)); ???????$ciphertext = mcrypt_generic($encrypter, $orig_data); ???????mcrypt_generic_deinit($encrypter); ???????mcrypt_module_close($encrypter); ???????return base64_encode($ciphertext); ???}
php7模式：
$cipher = "aes-256-cbc"; ???????$key = hash(‘sha256‘, ??‘@parkingwang.com‘ , true); ???????$encrypted = openssl_encrypt(json_encode($data), ‘AES-256-CBC‘, $key, 1, substr($key, 0, 16)); ???????$encrypt_msg = base64_encode($encrypted);
注意：加密后的字节码使用Base64转换成字符串
- 加密模式: CBC
- 填充模式: PKCS7Padding
- 加密密钥: 用户密钥 SHA256 的32 bytes
- AES IV : 加密密钥的前 16 bytes
- Base 64: Base64.DEFAULT
加密过程:
加密：padding->CBC加密->base64编码
解密：base64解码->CBC解密->unpadding
AES加密结果基准测试:
