使用模数和指数创建Google sign in公钥的通用方法

from Crypto.PublicKey import RSA

# 生成RSA密钥对
key = RSA.generate(2048)

# 获取公钥的模数和指数
modulus = key.publickey().n
exponent = key.publickey().e

# 创建Google sign in公钥
google_sign_in_public_key = {
    "modulus": modulus,
    "exponent": exponent
}

import java.security.KeyPair;
import java.security.KeyPairGenerator;
import java.security.NoSuchAlgorithmException;
import java.security.interfaces.RSAPublicKey;

// 生成RSA密钥对
KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance("RSA");
keyPairGenerator.initialize(2048);
KeyPair keyPair = keyPairGenerator.generateKeyPair();

// 获取公钥的模数和指数
RSAPublicKey publicKey = (RSAPublicKey) keyPair.getPublic();
String modulus = publicKey.getModulus().toString(16);
String exponent = publicKey.getPublicExponent().toString(16);

// 创建Google sign in公钥
String googleSignInPublicKey = "{\"modulus\":\"" + modulus + "\",\"exponent\":\"" + exponent + "\"}";
