I've a very small code in nodejs where I sign a string and then try to verify it, using node crypto and key pairs generated with openssl. No matter what I try, the result is always false, the signature can't be verified.

Generation of public/private key pairs:

openssl genrsa -out rsa_1024_priv.pem 1024



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

The resultant keys are (I don't care made them public BTW):

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

Then, this is my code for node:

var crypto = require('crypto');



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

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!

I've tried to use different algorithms and encoding. I've read the PEM files with fs, no luck also. What am I missing? BTW, those keys works perfectly using npm URSA module, so I know the keys are ok (can't use ursa in my project). Thanks!
