for my website "moneyart.info" I want to generate ECC public and private keys with JavaScript library sjcl. I tried following code:
*
crypto_keys = sjcl.ecc.elGamal.generateKeys(256);
var public_key = crypto_keys.pub.get();
var secret_key = crypto_keys.sec.get();
var public_key_hex = sjcl.codec.hex.fromBits(public_key.x) + sjcl.codec.hex.fromBits(public_key.y);
var secret_key_hex = sjcl.codec.hex.fromBits(secret_key);
alert(secret_key_hex);*
I get the error message:
TypeError: sjcl.ecc is undefined
I think I have to construct a class with new, but I dont know which one.
I found the mistake: ecc.elGamal is no standard sjcl function. I have to compile the sjcl.js file manually with additional functionality included. blog.peramid.es

I am trying to configure Mirth Connect Server 3.10.1 (Java version: 1.8.0_181), to write FHIR JSON docs to MongoDB. I've followed instructions from this post and have these drivers in custom-lib/
bson-4.2.0.jar
mongodb-driver-3.9.1.jar
mongodb-driver-core-4.2.0.jar
My conf/dbdrivers.xml has an entry like this,
<driver class"org.mongodb.Driver" name="MongoDB" template="mongodb://localhost:27017/" selectLimit="" />
I've setup my Channel Destination with a JavaScript Writer Connector Type and used this JS,
var mongoClient = new Packages.com.mongodb.MongoClient("localhost", 27017);
var database = mongoClient.getDatabase("synthea");
var collection = database.getCollection("synthea");
var jsonDoc = JSON.stringify(connectorMessage.getEncodedData(msg));
var doc = Packages.org.bson.Document.parse(jsonDoc);
collection.insertOne(doc);
var myDoc = collection.find().first();
logger.debug(myDoc.toJson());
mongoClient.close();
return;
When I deploy the Channel, I am getting this error.
Can anyone tell me what this means?
Any help or guidance very much (and humbly) appreciated.

I have a feeling this is due to the mismatched driver versions. Version 3.9 has the method indicated in the error, but 4.2 does not.
Once you get that sorted out, you are going to want to change this line
var jsonDoc = JSON.stringify(connectorMessage.getEncodedData(msg));
to this
var jsonDoc = connectorMessage.getEncodedData();
msg does not exist in a Javascript Writer, and connectorMessage.getEncodedData() does not take any parameters and returns a String. connectorMessage is an instance of ImmutableConnectorMessage from the Mirth User API.
I am trying to get the FetchXML query for a specific query expression fro Dynamics CRM. I have manged to do it using the XRM SDK in a C# project as follows.
string connectionStr = #"Server=https://mycompany.com/XRMServices/2011/Organization.svc; Username=theUserName; Password=pwd";
Microsoft.Xrm.Client.CrmConnection conn = Microsoft.Xrm.Client.CrmConnection.Parse(connectionStr);
var service = new Microsoft.Xrm.Client.CrmOrganizationServiceContext(conn);
var query = new QueryExpression();
QueryExpressionToFetchXmlRequest req = new QueryExpressionToFetchXmlRequest();
query.EntityName = "my_entity";
query.ColumnSet = new ColumnSet("_accountnumber", "_id");
FilterExpression filter = new FilterExpression();
filter.Conditions.Add(new ConditionExpression("_Oactivedate", ConditionOperator.NotNull));
filter.Conditions.Add(new ConditionExpression("_Oinactivedate", ConditionOperator.Null));
filter.Conditions.Add(new ConditionExpression("_state", ConditionOperator.Equal, 0));
FilterExpression filter1 = new FilterExpression(LogicalOperator.Or);
var filter2 = new FilterExpression(LogicalOperator.And);
filter2.Conditions.Add(new ConditionExpression("_lastname", ConditionOperator.Equal, lastName));
filter2.Conditions.Add(new ConditionExpression("_accountnumber", ConditionOperator.Equal, accountId));
var filter3 = new FilterExpression(LogicalOperator.And);
filter3.Conditions.Add(new ConditionExpression("_accountactivedate", ConditionOperator.NotNull));
filter3.Conditions.Add(new ConditionExpression("_accountinactivedate", ConditionOperator.Null));
filter1.AddFilter(filter2);
filter1.AddFilter(filter3);
filter.AddFilter(filter1);
query.Criteria = filter;
req.Query = query;
QueryExpressionToFetchXmlResponse resp = (QueryExpressionToFetchXmlResponse)service.Execute(req);
//fetchxml string
string myfetch = resp.FetchXml;
My requirement doesn't allow for a .Net DLL, therefore I would like to do this in JS. I have tried to look at the JS SDK and it is not as friendly as the C# one (maybe it's just me :). I would really appreciate anyone who can attempt to write a JS equivalent of my code above, or guide to a good material that can help me figure it out myself. My main interest is the generation of the FetchXml query from a dynamic strongly typed QueryExpression object. Thanks!
You should be able to build your query in Advanced find & Download the fetchxml from there to use in JavaScript. Read more
You can use XrmToolBox - FetchXml Builder as well for building queries (this will give SQL, QueryExpression equivalent too), then generate language compatible output using this online formatter tool
Code sample to use fetchxml in JavaScript can be find in this blog. For Example:
var encodedFetchXml = encodeURI(fetchContact);
var reqURL = clientURL + “/api/data/v8.2/contacts?fetchXml=” + encodedFetchXml;
var req = new XMLHttpRequest();
req.open(“GET”, reqURL, false);
QueryExpression, FetchXml, LINQ are all choices to write the same query. As you know - QueryExpression cannot be used in JavaScript, but fetchxml can be used in both C# & JS.
In addition to #Arun's excellent answer, another possibility would be to keep your logic in C# and register it in the system as a custom Action, which you then call from JavaScript.
Problem
I'm trying to create a simple trustless file sharing application. I'm using EasyRSA (https://github.com/paragonie/EasyRSA) to create a key-pair and then encrypt my data with the public key. I'm sending the private key to my JS wherein I'm using Node-RSA (https://github.com/rzcoder/node-rsa). Here, I try to decrypt using the previously created private key. But this happens:
Error
Uncaught Error: Error during decryption (probably incorrect key). Original error: Error: Incorrect data or key
at NodeRSA.module.exports.NodeRSA.$$decryptKey (drop.js:23265)
at NodeRSA.module.exports.NodeRSA.decrypt (drop.js:23213)
at window.onload (drop.js:22270)
My JS code looks something like this:
var NodeRSA = require('node-rsa');
window.onload = function() {
var key_val = $('#key').val();
var ciphertext = $('#encrypted').val();
var key = new NodeRSA();
key.importKey($('#key').val(), 'pkcs1');
var ciphertext_base = key.encrypt(ciphertext, 'base64');
var decrypted_base = key.decrypt(btoa(ciphertext));
console.log(decrypted);
}
I think this has got something to do with the incompatibility between the formats/key-sizes/algos used to create the keys. If someone could help me 'hack' this and make it work, I would be very grateful to you.
I am trying get a var from a webview but I only can modify like this:
browser.loadUrl("javascript:var x = document.getElementById('login').value = 'something';");
but I need get any js var like this :
String myAndroidvar = browser.loadUrl("javascript:var x = document.getElementById('login').value");
but this syntax is incorrect, I need the correct method.
You have to add a javaScriptInterface to you webview. See this blog for a decent description.
You can also get stuff from javascript by calling an interface function you defined using:
web.loadUrl("javascript: window.jsinterface.getValue(document.getElementById('login').value)");
I am trying to verify an RSA signature in Javascript but I can't seem to get it to work. I think I have to do something with my key and signatures but I am very confused.
Here is a link to this library
var publicKey = "MIIBIjBNBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAoPNkJzHqbY/6mAjJwb4zUbOiOjvmg3b8fvydYdGXdv04r6vzgn/FD5NPJM7bojAxi6sZ8vV+fYVIQey6HnrLSsdU/QXhT3p22a+kB4ym8SbKsOy2fWqL950nZCPYW/DC9txHy+ceFuKMAarFWAMJRe+MaVIbDIAAi8tMNjZ204GkmqveyAeA6JppzthAuiX69H8Zb3Hbs49CHNwLnSpKz5HBTfcgWqHkar2HlEFccvWC++Kq47MIkEcKScS/oneDb/TiL5ClOas1gMxfwiVtkFI6zNxxJOJDSTlY66oHCVCfTruk2pQbtOtwJEGrOwq6B536QL/EkeEKMgiqlpZJbQIDAQAB";
var stringToVerify = "aaa";

var KJUR = require("cloud/jsrsasign-4.7.0/npm/lib/jsrsasign.js");
var verifier = new KJUR.crypto.Signature({alg: "SHA1withRSA", prov: "cryptojs/jsrsa"});
verifier.init(publicKey);
verifier.updateString(stringToVerify);
console.log(verifier.verify(signature));
Thanks in advance
You need to base 64 decode both the public key and the signature. They key and signature should then be re-encoded as hexadecimals. Then you hopefully should be able to use this method to generate a public RSAKey object.
I'm saying hopefully, as the the API description is just horrible. Personally I would not recommend to use such an API.
