Digital Signing and Verification
Tungsten produces Invoice Images in PDF format. These are digitally signed to conform to the requirements of European tax law as implemented by a number of EU countries.
For more information on Tungsten Network Signing, download the "Digital Signing and Verification Document".
Digital Signing and Verification Document
In order to verify the signature you need to download and install the certificates used into Adobe Reader. Please download all files called "OB10_All_Certs.zip" and install the certificates by following the instructions in Section 8 of "Digital Signing and Verification Document".
You need these digital certificates to read Invoices which have been digitally signed by the Tungsten Network (in HTML email or other signed formats).
Choose a format which works with your computer, download the zip file and install all three certificates.
Instructions for Internet Explorer:
- Open each certificate file
- Press Install Certificate
- Press Next, Next, Next until each certificate is installed
Once you have installed the Identrus-Root, RBS-Identrus and Tungsten-RBS certificates, a chain is established from the root certificate to the certificate used to digitally sign OB10 invoice data, emails or images.
