XML error

[Hellomik2002]

I installed webcrypto with npm by but still have issue when I try new XmlDSigJs.SignedXml().Sign(...)

XmlError {
  prefix: 'XMLJS',
  code: 14,
  name: 'XmlError',
  message: 'XMLJS0014: WebCrypto module is not found',
  stack: 'Error: XMLJS0014: WebCrypto module is not found\n' +
    '    at new XmlError (C:\\projects\\notr\\node_modules\\xml-core\\dist\\index.js:216:22)\n' +

}

You might have fallen into the same trap I did a while ago. First, if you do npm install webcrypto it doesn't provide WebCrypto. Then, the 3 libraries that do are listed in this post by me and I think the only one that works with xmldsigjs is webcrypto-ossl. (That post has now other libraries failed to work with xmldsigjs.) Even worse, these libraries have different initialisation methods so one can't serve as the drop-in replacement of another without tweak.
