RSA加密/解密与Javascript和PHP兼容

const { generateKeyPair } = require('crypto');

generateKeyPair('rsa', {
  modulusLength: 2048,
  publicKeyEncoding: {
    type: 'spki',
    format: 'pem'
  },
  privateKeyEncoding: {
    type: 'pkcs8',
    format: 'pem'
  }
}, (err, publicKey, privateKey) => {
  console.log(publicKey);
  console.log(privateKey);
});

$config = array(
    "digest_alg" => "sha256",
    "private_key_bits" => 2048,
    "private_key_type" => OPENSSL_KEYTYPE_RSA,
);

$res = openssl_pkey_new($config);

openssl_pkey_export($res, $privateKey);

$publicKey = openssl_pkey_get_details($res)["key"];

echo $privateKey;
echo $publicKey;
