Could not find ByteRange placeholder: /ByteRange [0 /********** /********** /**********] about node-signpdf

[vbuch]

Did you add it?

[angeltg83]

I can't,
I have a pdf created with another library, this is my code,

let signer = require('node-signpdf').default;

console.log('\n\n\nsigner', signer);
let URL_PDF = "/home/xxx/Desktop/PDF_FIRMA/prueba.pdf";
let TOKEN_P12 = "/home/xx/Desktop/PDF_FIRMA/PLAN VITAL VITALPLAN S.A.P12";

var pdfBuffer = fs.readFileSync(URL_PDF);

console.log('pdfBuffer', pdfBuffer);

const signedPdf = signer.sign(
  pdfBuffer,
  fs.readFileSync(TOKEN_P12),
  { passphrase: 'pass.31', asn1StrictParsing: true, },
);

// return res.json(signer);

Please help!!

.sign expects the placeholder to be there. read the readme. Also take a look here: #22

[angeltg83]

use the helper of your plainAddPlaceholder library, as the code is shown

var signer = require('node-signpdf').default;
var placeholder = require('node-signpdf').plainAddPlaceholder.default;
var fs = require('fs');
var PATH_TO_PDF_FILE = "prueba.pdf";
var PATH_TO_P12_CERTIFICATE = "/pc/TOKEN.P12";

console.log('signer UUU ', placeholder);

var pdfBuffer = fs.readFileSync(PATH_TO_PDF_FILE),
  pdfBuffer = placeholder({
    pdfBuffer,
    reason: '',
    signatureLength: 1612,
  });



var signedPdf = signer.sign(
  // fs.readFileSync(PATH_TO_PDF_FILE),
  pdfBuffer,
  fs.readFileSync(PATH_TO_P12_CERTIFICATE), {
    passphrase: 'pas.311',
    asn1StrictParsing: true,
  }
);

console.log('signedPdf ', signedPdf);

fs.writeFileSync('PC/Firmando[PDF]/21820[RQ000009]FIRMADO.pdf', signedPdf);

and then show the error:

please!!, help,

Well, this is not yet supported as the error says. Your pdf already contains annotations and i have not written code to handle that situation... If someone has the time to do it, a PR would be more than welcome.

[angeltg83]

I already made it, edited the library and I was successful. only that the pdf when verifying it with adobe the signature is obtained inconsistent.
