# hybrid-cipher
Hybrid Encryption Mode with Public-Key Encryption and Symmetric Encryption.
## Install
```
pip install hybrid-cipher
```
## 加密原理
### 加密步骤
1. 生成随机32位临时密钥。
2. 使用RSA公钥加密临时密钥。
3. 使用临时密钥及AES GCM加密算法加密数据内容。
4. 把临时密钥的密文及数据密文相关字段拼接在一起，作为整体密文。
### 解密步骤
1. 分割密文为：临时密钥密文、数据密文相关字段。
2. 使用RSA私钥解密临时密钥密文，得到临时密钥明文。
3. 使用临时密钥明文及AES GCM解密算法解密数据密文相关字段，得到数据明文。
## Usage
```
In [1]: from Crypto.PublicKey import RSA
...: from hybrid_cipher import HybridCipher
...:
...: sk = RSA.generate(1024)
In [2]:
In [2]: cipher = HybridCipher(sk)
In [3]: cipher.encrypt({"a": "b"})
