RSA标准加密解密，高强度秘钥4096确保万无一失

上代码：

#pip install cryptography
from cryptography.hazmat.primitives.asymmetric import rsa
from cryptography.hazmat.primitives import serialization
from cryptography.hazmat.primitives import hashes
from cryptography.hazmat.primitives.asymmetric import padding# 生成RSA密钥对
def generate_rsa_keypair():# 生成私钥private_key = rsa.generate_private_key(public_exponent=65537,key_size=4096,)# 生成公钥public_key = private_key.public_key()return private_key, public_key# 将密钥保存到文件
def save_key_to_file(key, filename, is_private=True):pem = key.private_bytes(encoding=serialization.Encoding.PEM,format=serialization.PrivateFormat.TraditionalOpenSSL,encryption_algorithm=serialization.NoEncryption()) if is_private else key.public_bytes(encoding=serialization.Encoding.PEM,format=
