pidCrypt in Node red

There is a JavaScript function below: How do I import the javascript library into node red?

var key = encryptionKey();
var asn, tree;
rsa = new pidCrypt.RSA();
decodedKey = pidCryptUtil.decodeBase64(ekey);

asn = pidCrypt.ASN1.decode(pidCryptUtil.toByteArray(decodedKey));
tree = asn.toHexTree();

rsa.setPublicKeyFromASN(tree);

console.log= pidCryptUtil.encodeBase64(pidCryptUtil.convertFromHex(rsa.encrypt(passw += '|' + etime)));
