Qweb PDF reports signer

This module extends the functionality of report module to sign PDFs using a PKCS#12 certificate.


To install this module, you need to install Java JDK:

apt-get install openjdk-7-jre-headless


In order to start signing PDF documents you need to configure certificate(s) to use in your company.

  • Go to Settings > Companies > Companies > Your company
  • Go to Report configuration tab
  • Click Edit
  • Add a new item in PDF report certificates list
  • Click Create
  • Set name, certificate file, password file and model
  • Optionally you can set a domain and filename pattern for saving as attachment

For example, if you want to sign only customer invoices in open or paid state:

  • Model: account.invoice
  • Domain: [('type','=','out_invoice'), ('state', 'in', ('open', 'paid'))]
  • Save as attachment: (object.number or '').replace('/','_') + '.signed.pdf'

Note: Linux user that executes Odoo server process must have read access to certificate file and password file


User just prints PDF documents (only Qweb PDF reports supported) as usual, but signed PDF is automatically downloaded if this document model is configured as indicated above.

If 'Save as attachment' is configured, signed PDF is saved as attachment and next time saved one is downloaded without signing again. This is appropiate when signing date is important, for example, when signing customer invoices.
