signcode

Sign Windows executables and installers from a Mac or a machine with osslsigncode installed.

Works with .pem, .p12, and .pfx code signing files.

Signs with sha1 and sha256 signatures by default.

Installing

npm install --save-dev signcode

Using

var signcode = require('signcode')

var options = {
  cert: '/Users/kevin/certs/cert.pem',
  key: '/Users/kevin/certs/key.pem',
  overwrite: true,
  path: '/Users/kevin/apps/myapp.exe'
}

signcode.sign(options, function (error) {
  if (error) {
    console.error('Signing failed', error.message)
  } else {
    console.log(options.path + ' is now signed')
  }
})

signcode.verify({ path: '/Users/kevin/apps/myapp.exe' }, function (error) {
  if (error) {
    console.error('Not signed', error.message)
  } else {
    console.log(options.path + ' is signed')
  }
})

Cert helpers commands

These commands are helpful when working with certificates.

Create cert and key with no password

openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -nodes

Create cert and key with a password

openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem

Create a p12 with no password

openssl pkcs12 -export -out ./test/fixtures/cert.p12 -inkey ./test/fixtures/key.pem -in ./test/fixtures/cert.pem

Show fingerprint of a cert

openssl x509 -noout -in ./test/fixtures/cert.pem -fingerprint -sha1

openssl x509 -noout -in ./test/fixtures/cert.pem -fingerprint -sha256
