How to set a value for SigningTime in YYYY-MM-DDThh: mm: ss-05: 00 format?. The signature has the SigningTime element in format YY-MM-DDThh: mm: ssxxxz but the tax entity requires the YYYY-MM-DDThh: mm: ss-05: 00 format. Please, how to set?.

XAdES uses dateFormat function to serialize XadesDateTime element.

I've updated the XAdES module to v2.0.15 and added the SigningTime options to Sign method.

Example

const { Crypto } = require("@peculiar/webcrypto");
const xades = require("xadesjs");

async function main() {
  const crypto = new Crypto();

  // Set crypto engine for XAdES
  xades.Application.setEngine("NodeJS", crypto);

  // Generate RSA keys
  const algorithm = {
    name: "RSASSA-PKCS1-v1_5",
    hash: "SHA-256",
    publicExponent: new Uint8Array([1, 0, 1]),
    modulusLength: 2048,
  };
  const keys = await crypto.subtle.generateKey(algorithm, false, ["sign", "verify"]);

  // Sign XML
  const xmlDoc = xades.Parse(`<root><child attr="Some"/></root>`);
  const signedXml = new xades.SignedXml();

  const signature = await signedXml.Sign(
    algorithm,                              // algorithm
    keys.privateKey,                        // key
    xmlDoc,                                 // document
    {                                       // options
      keyValue: keys.publicKey,
      references: [
        { hash: "SHA-256", transforms: ["enveloped"] }
      ],
      productionPlace: {
        country: "Country",
        state: "State",
        city: "City",
        code: "Code",
      },
      signingTime: {
        format: "isoDateTime"
      }
    });

  console.log(signature.toString());
}

main()
  .catch(e => console.error(e));

Update xadesjs from v2.0.14 -> v2.0.15 and it works for me. Thank you.

Would love to hear how your using xadesjs.

I look on the file dateFormat but I can't find the xmlDateTime,

The problem is isoDateTime dont put the char : in timezone, and it is invalid for some xml schemas.

Example: 2020-07-13T08:17:03-05:00
