生成RSA公钥和私钥对公钥进行base64编码

要生成RSA公钥和私钥，可以使用Python中的cryptography库。下面是一个示例代码：

from cryptography.hazmat.primitives import serialization
from cryptography.hazmat.primitives.asymmetric import rsa
import base64

# 生成RSA密钥对
private_key = rsa.generate_private_key(
    public_exponent=65537,
    key_size=2048,
)

# 获取公钥并进行base64编码
public_key = private_key.public_key()
public_key_pem = public_key.public_bytes(
    encoding=serialization.Encoding.PEM,
    format=serialization.PublicFormat.SubjectPublicKeyInfo
)
public_key_base64 = base64.b64encode(public_key_pem).decode('utf-8')

# 获取私钥
private_key_pem = private_key.private_bytes(
    encoding=serialization.Encoding.PEM,
    format=serialization.PrivateFormat.PKCS8,
    encryption_algorithm=serialization.NoEncryption()
)
private_key_base64 = base64.b64encode(private_key_pem).decode('utf-8')

print("公钥(base64编码)：")
print(public_key_base64)
print("私钥(base64编码)：")
print(private_key_base64)

运行上述代码，将会输出生成的RSA公钥和私钥的base64编码形式
