在Python中,通过Cryptography库可以方便地实现SM4(也称为AES-256-GCM)的ECB(Electronic Codebook)模式加密。首先,你需要安装`cryptography`库,如果还没有安装,可以使用pip进行安装:
```bash
pip install cryptography
```
接下来,你可以按照以下步骤使用SM4 ECB模式:
1. 导入所需的模块:
```python
from cryptography.hazmat.primitives.ciphers import algorithms, modes
from cryptography.hazmat.primitives.kdf.pbkdf2 import PBKDF2HMAC
from cryptography.hazmat.primitives.ciphers.algorithms import SM4
from cryptography.hazmat.backends import default_backend
```
2. 定义密码和密钥:
```python
password = b"your_password"
salt = b'some_salt'
iterations = 100000
key = PBKDF2HMAC(
algorithm=algorithms.SM4(),
length=32,
salt=salt,
iterations=iterations,
backend=default_backend()
).derive(password)
```
3. 创建SM4 ECB模式的加密器:
```python
cipher = SM4(key)
e_cbcmode = modes.ECB()
```
4. 加密数据:
```python
plaintext = b"your_plaintext_to_encrypt"
ciphertext = cipher.encrypt(plaintext, e_cbcmode)
```
5. 如果需要,保存或传输加密后的数据。
