I can't decrypt unencrypted #215

alantoledo007 · 2022-04-17T19:29:40Z

I created a helper to get the public and private key. The pems files have been created with new NodeRSA ({b:1024}):

const fs = require("fs");
const NodeRSA = require("node-rsa");

const getKeys = () => {
  const publicPem = fs.readFileSync("./public.pem", "utf8");
  const privatePem = fs.readFileSync("./private.pem", "utf8");

  const privateKey = new NodeRSA(privatePem);
  const publicKey = new NodeRSA(publicPem);

  return {
    privateKey,
    publicKey,
    privatePem,
    publicPem,
  };
};

const RSA = {
  getKeys,
};

module.exports = { RSA };

i can encrypt with publicKey.encrypt(data, "base64"). And, i can decrypt with privateKey.decrypt(encryptedData,'utf8').

but...

I can't decrypt if I didn't create any encryption before. Just to give you an idea, I have to do this for the decryption to work:

publicKey.encrypt(""); //bug
const decryptedData= privateKey.decrypt(encryptedRSA, "utf8");

without publicKey.encrypt(""); //bug the terminal returns next error:

            throw Error('Error during decryption (probably incorrect key). Original error: ' + e);
            ^

Error: Error during decryption (probably incorrect key). Original error: Error: error:25078067:DSO support routines:win32_load:could not load the shared library

Summary

// Works
const encryptedData = publicKey.encrypt(data, "base64");
const decryptedData = privateKey.decrypt(encryptedData , "utf8");

// Not works
// const encryptedData = publicKey.encrypt(data, "base64");
const decryptedData = privateKey.decrypt("your base64 encryption", "utf8");

// Works
publicKey.encrypt("");
const decryptedData = privateKey.decrypt("your base64 encryption", "utf8");

reproduce error:

Encrypt anything.
Copy the encrypted result.
remove or comment out the lines of code that do the encryption
try decrypt. (not works)

@alantoledo007 hi! Can you provide minimal snippet with bug?

alantoledo007 · 2022-04-17T21:06:41Z

publicKey.encrypt("");

everytime i want decrypt, i need create any encrypt for can decrypt anything. If I remove that line, I get this error::

            throw Error('Error during decryption (probably incorrect key). Original error: ' + e);
            ^

I mean the working piece of the code with the bug

My test works fine

const NodeRSA = require("../src/NodeRSA")

const key = new NodeRSA("-----BEGIN RSA PRIVATE KEY-----\n" +
"MIIBPQIBAAJBAPjFVq2K1qm59eS70nhpnh+Yx4/jaoulc2nzWw0AG6wwr29igI7q\n" +
"moBFFwyGJtTGY5DczVC1yA/Y0O9nynwn+3MCAwEAAQJBAN9K+i9RRLcZ5N3HvPY6\n" +
"DyVbVB0SSstH2d2LAvobU7tsPrKnudtBPb9jj2m9LEeM60JZNS3OthkTm5b0PgoJ\n" +
"IiECIQD9HyclvA9XdQ+iieY/WZN+IN1AUWFR+1sf+bfnMNV3wwIhAPuZhSx2ihYH\n" +

"ANHW+0rRgieQtrs/Gz5bbtMKG7T8zirWkd3Av+FEVwQM\n" +
"-----END RSA PRIVATE KEY-----");

//console.log(key.encrypt("abc", "base64"))

console.log(key.decrypt("gUUaWQFC4NP22bUW+5qJUOTJQpk9DYWY7PvvLzCbEIYtg1GYSarVPg42DfpGpgsMAUubxZBA7HdX8oSJ/jhSAw==", "utf8"))

Also, original error: error:25078067:DSO support routines:win32_load:could not load the shared library looks like some node error

I can't run & debug this. Can you provide snippet without dependencies?

alantoledo007 · 2022-04-17T21:38:28Z

Step1

const NodeRSA = require("node-rsa");

const privateKey = new NodeRSA("your private key");
const publicKey = new NodeRSA("you public key");

const encrypt = ( data ) => {
  const encryptedData= publicKey.encrypt(
    JSON.stringify(data),
    "base64"
  );

  return encryptedData
};

const decrypt = (encryptedData) => {
  const decryptedData= privateKey.decrypt(encryptedData, "utf8");
  return decryptedData;
};

const encryptedData = encrypt({foo:"var"})
console.log(encryptedData) // returns a base64 encryption

Step2

const NodeRSA = require("node-rsa");

const privateKey = new NodeRSA("your private key");
const publicKey = new NodeRSA("you public key");

const encrypt = ( data ) => {
  const encryptedData= publicKey.encrypt(
    JSON.stringify(data),
    "base64"
  );

  return encryptedData
};

const decrypt = (encryptedData) => {
  const decryptedData= privateKey.decrypt(encryptedData, "utf8");
  return decryptedData;
};

// const encryptedData = encrypt({foo:"var"})
// console.log(encryptedData) // returns a base64 encryption
console.log(decrypt("base64 encryption")) //error: throw Error('Error during decryption (probably incorrect key). Original error: ' + e);

My solution:

const NodeRSA = require("node-rsa");

const privateKey = new NodeRSA("your private key");
const publicKey = new NodeRSA("you public key");

const encrypt = ( data ) => {
  const encryptedData= publicKey.encrypt(
    JSON.stringify(data),
    "base64"
  );

  return encryptedData
};

const decrypt = (encryptedData) => {
  publicKey.encrypt(""); //############## SOLUTION HERE ############
  const decryptedData= privateKey.decrypt(encryptedData, "utf8");
  return decryptedData;
};

// const encryptedData = encrypt({foo:"var"})
// console.log(encryptedData) // returns a base64 encryption
console.log(decrypt("base64 encryption")) //works

For me it just works fine. As I said, probably node bug, or may be your system. Try to install different node version or test it on other system.

reezon · 2022-12-06T11:20:03Z

i fix it。because node-rsa use pkcs1_oaep. so need to add code:

key.setOptions({ encryptionScheme: 'pkcs1' });
