What is KawanDoc?

KawanDoc is a software and service that allows you to easily and safely transmit (strong encryption) your confidential Word, Excel, PowerPoint documents in PDF format to your correspondents:

  • PDF are encrypted with a password and are sent by e-mail.
  • Passwords are sent by SMS message, using the numbers of the recipients mobile device.

Using 2 different channels to send encrypted PDF documents (via e-mail) on the one hand and the decryption password (via SMS) on the other hand guarantees a very strong security. It is a variant of this technique which is used by banks to secure authentication for access to online accounts.

KawanDoc has the advantage that the recipient does not require any software or service to decipher the PDF. It is enough to open the encrypted PDF: the password received via SMS message will be requested prior to authorizing the display.


Why use KawanDoc to disseminate encrypted documents via e-mail?

Distributing confidential encrypted documents via e-mail is very complicated: the correspondent has to equip themselves with decryption software, or subscribe to a service. This is very restrictive for recipients and requires the implementation of logistics of an encryption system (PKI, etc.).

KawanDoc does away with this complexity: the correspondent can always decrypt PDF received; there is no need for any software or service required for decrypting an encrypted PDF!
A simple click and upon the opening of the PDF, a password is requested to decrypt the content. The user only needs to read their SMS message to retrieve the password.

KawanDoc - among others - can be a great alternative to paper mail for the transmission of mail.


What software or service do the recipients of the e-mails need in order to decrypt PDF?

None! Simply double-click each received PDF file and the password will be automatically requested to open the file.


What are the requirements to receive and open an encrypted PDF by KawanDoc?

None! The decryption works on all personal computers and mobile devices which can read a PDF file: Windows, OS X, Linux, Android, iOS, BlackBerry, Windows CE,...


What are the country's that support the transmission of SMS messages?

SMS messages can be sent to 220 countries.
See list of supported countries.


Must we manually enter the number of the correspondent's mobile device to ensure the transmission of the SMS message?

No, the entry can be automated very easily:

  • KawanDoc includes an address book that allows you to register names, e-mails, and cell phone numbers.
  • Import wizards allow you to import the contact information of your contacts from your Gmail or Outlook Office (Windows) accounts in one click.
  • The input supports auto-completion: you start typing the name or e-mail of a person and KawanDoc displays all the possible contacts. A click on one of the people, and the Name, E-mail Address, as well as the Mobile Phone Number are inserted in the Recipient window.

What are the system requirements of the KawanDoc software for encryption and transmission of PDF?

  • A Desktop PC with choice:
     
  • Microsoft Windows (Vista, 7, 8, 8.1, 10).
  • Apple OS X (+ 10.8).
  • Linux (all distributions and versions that support Java 7 +).

  • 128 MB of memory (256 MB recommended).
     
  • 200 MB of disk space.
     

What are the requirements to install KawanDoc on Windows or OS X?

There are no requirements:

  • The installer contains all the necessary software.
  • The software installs and runs under a "standard" account, without Administrative privileges.

What are the requirements to install KawanDoc on Linux?

KawanDoc Linux requires the prior installation of Java 7 or Java 8.
The software installs and operates under a standard account and never requires sudo or root access.


What are the network prerequisites to use KawanDoc in my company?

The client software KawanDoc uses standard https requests to communicate with the KawanDoc server. There is no special prerequisite for using KawanDoc, just check these issues with your System Administrator:


Does KawanDoc work behind a proxy?

Yes! KawanDoc works behind proxy.


Does KawanDoc detect my PC or Mac proxy settings?

Yes! KawanDoc will automatically detect your proxy settings.


Does KawanDoc support proxies with authentication?

Yes! KawanDoc detects whether authentication is required and therefore requests if a username/password is needed.


What is the type of encryption used by KawanDoc?

PDF are encrypted with the AES (Advanced Encryption Standard) algorithm with 128 or 256-bit long keys.

AES is the official algorithm for governmental organizations in the USA.

This type of encryption with long keys is considered "strong" and is considered to be impenetrable, including by national intelligence agencies.


How is the encryption created? Do you use ADOBE software?

KawanDoc does not use Adobe software to manage PDF encryption, but uses the PDF specifications that are public.

PDF encryption is completed with the Java Open Source Bouncy Castle library.


I would like to integrate the transmission of encrypted PDFs in an application. Do you offer an API instead of your client software?

Yes, see our API page for more details.


Would you accept that our company audit your software (security, cryptography)?

Yes, contact us for details.
