node-rsa and openssl compatibility

Question

I have a set of public/private keys, that works flawless when encrypting/decrypting some data using only one of the 2 ways for both encryption and decryption.

I still have no luck trying to encrypt the data with the one of the two and decrypt it with the other.

Example schenario:

a) I create some encrypted data using the public key with the following node.js code:

#!/usr/bin/env node

var NodeRSA = require('node-rsa');
var fs = require('fs');

function createUsingPubKey(Pub, data) {
    var pk = new NodeRSA();
    pk.importKey(Pub);
    encrypted = pk.encrypt(data, 'base64');
    return encrypted;
}

var sampledata = "SECRET STUFF";

var genkey = createUsingPubKey(fs.readFileSync('id_rsa.pub'), sampledata)
console.log(genkey);

b) Then i try to decrypt it using openssl utility with this:

node test.js | openssl base64 -d -A | openssl rsautl -inkey id_rsa

But i get:

RSA operation error
1068:error:0406706C:rsa routines:RSA_EAY_PUBLIC_DECRYPT:data greater than mod len:.\crypto\rsa\rsa_eay.c:680:

I thought that they probably would use different algorithms for the encryption/decryption procedure so i headed to the node-rsa documentation here: https://www.npmjs.com/package/node-rsa and i found this option:

encryptionScheme — padding scheme for encrypt/decrypt. Can be 'pkcs1_oaep' or 'pkcs1'. Default 'pkcs1_oaep'.

I then tried to decrypt passing the -oaep option in openssl util like this:

node test.js | openssl base64 -d -A | openssl rsautl -oaep -inkey id_rsa

But i still get:

RSA operation error
5216:error:0406706C:rsa routines:RSA_EAY_PUBLIC_DECRYPT:data greater than mod len:.\crypto\rsa\rsa_eay.c:680:

My knowledge on cryptography is really basic. Any help would be appreciated :)

EDIT 1: The node.js module can be found here: https://github.com/rzcoder/node-rsa

EDIT 2: As Maarten Bodewes requested, here is some sample data:

Plaintext data to be encrypted:

You're no good, you're no good, you're no good Baby, you're no good (I'm gonna say it again) You're no good, you're no good, you're no good Baby, you're no good

A private key generated with

openssl genrsa -out key 512

And its equivalent pub key

Answer 1

Just add -decrypt argument for openssl

node test.js | openssl base64 -d -A | openssl rsautl -decrypt -oaep -inkey id_rsa

works pretty nice for me.
