@viniciusknob Thanks for reporting the issue. Will look into it.

In the meantime, could you please check if you've installed qpdf in your machine?

[viniciusknob]

@AshikNesin you right! I've forgot to install qpdf, but after installing I saw the following error:

$ node remove-pdf-password PWD remove_pwd_test/n/encrypted.pdf
C:\project\test\node_modules\remove-pdf-password\index.js:10
                throw new Error(data.toString());
                ^

Error: WARNING: remove_pwd_test/n/encrypted.pdf: file is damaged

My code is:

const removePdfPassword = require('remove-pdf-password');

let pwd = process.argv.filter((item,index) => index == 2);
let files = process.argv.filter((item,index) => index >= 3);

files.forEach(filename => {

    const params = {
        inputFilePath: filename,
        password: pwd,
        outputFilePath: filename.replace('.pdf','_unlocked.pdf'),
    }
    
    removePdfPassword(params);

});

So, I decided to use native qpdf commands that solved my problem:

qpdf --password=PWD --decrypt --no-warn encrypted.pdf descrypted.pdf

Thanks anyway.

I've tested this only on MacOS. I think it's breaking on Windows. Thanks for letting me know. @viniciusknob
