node-rsa errors when trying to decrypt message with private key

To answer your question @Curious_Programmer be default node-rsa uses pkcs1_oaep for encryption and decryption while jsencrypt uses pkcs1. Thankfully node lets you change the encryptionScheme, what you need to do is add ...

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

under

var myDecrypter = new NodeRSA({b: 512});

and all will work like a charm, I hoped I helped you ;)
