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:
