node.js - Node rsa : InvalidAsn1Error: encoding too long

Question

我正在使用node-rsa模块来解密 key 。

我使用以下命令从 p12 文件创建了一个私钥

openssl pkcs12 -in xxx.p12 -nocerts -out privateKeyPkcs12.pem

它给出了 rsa 私钥，所以我尝试使用这个 rsa 私钥来创建 key ，如下所示

var NodeRSA = require('node-rsa');
var pemStr = '-----BEGIN RSA PRIVATE KEY-----\n' +

'-----END RSA PRIVATE KEY-----\n';

var key = new NodeRSA(pemStr);
console.log(key);

但是我收到了这个错误

   throw newInvalidAsn1Error('encoding too long');
        ^

  at Module.load (module.js:356:32)

如何创建 key ？

Answer 1

删除键字符串末尾的换行符 (\n)

'-----END RSA PRIVATE KEY-----\n';

到

'-----END RSA PRIVATE KEY-----';
