如何安装Python3.9的PyCrypto？

pip install pycryptodome

conda install -c conda-forge pycryptodome

sudo apt-get install python-dev libssl-dev

python3 -m venv myenv
source myenv/bin/activate
pip install pycryptodome

pip install --target=/path/to/installation/directory pycryptodome

from Crypto.Cipher import AES
from Crypto.Random import get_random_bytes
from Crypto.Util.Padding import pad, unpad

# 生成密钥
key = get_random_bytes(16)

# 创建 AES 加密对象
cipher = AES.new(key, AES.MODE_CBC)

# 待加密的数据
data = b'This is a secret message'

# 填充数据
padded_data = pad(data, AES.block_size)

# 加密数据
iv = cipher.iv
encrypted_data = cipher.encrypt(padded_data)

# 解密数据
cipher = AES.new(key, AES.MODE_CBC, iv)
decrypted_padded_data = cipher.decrypt(encrypted_data)
decrypted_data = unpad(decrypted_padded_data, AES.block_size)

print("Original Data:", data)
print("Decrypted Data:", decrypted_data)
