javascript - 无法使用 key 对验证 Node.js Crypto 的签名

Question

我在nodejs中有一个非常小的代码，我在其中签署一个字符串，然后尝试使用openssl生成的 Node 加密和 key 对来验证它。无论我尝试什么，结果总是“假”，无法验证签名。

生成公钥/私钥对:

openssl genrsa -out rsa_1024_priv.pem 1024

openssl rsa -in rsa_1024_priv.pem -out rsa_1024_pub.pem -outform PEM -pubout

生成的 key 是(顺便说一句，我不在乎将它们公开):

-----BEGIN RSA PRIVATE KEY-----

然后，这是我的 Node 代码:

var crypto = require('crypto');

var privateKey = '-----BEGIN RSA PRIVATE KEY-----\n'+
'MIICXQIBAAKBgQDCtTEic76GBqUetJ1XXrrWZcxd8vJr2raWRqBjbGpSzLqa3YLv\n'+

'-----END PUBLIC KEY-----';

var signer = crypto.createSign('sha256');
signer.update('hola');
var sign = signer.sign(privateKey,'base64');

var verifier = crypto.createVerify('sha256');
verifier.update(sign);
var ver = verifier.verify(publicKey, sign,'base64');
console.log(ver);//<--- always false!

我尝试使用不同的算法和编码。我已经用“fs”阅读了 PEM 文件，也没有运气。我错过了什么？顺便说一句，这些 key 使用 npm URSA 模块可以完美运行，所以我知道 key 没问题(不能在我的项目中使用 ursa)。谢谢!

Answer 1

您需要验证您签署的相同数据:verifier.update(sign); 应该是 verifier.update('hola');
