Windows app for encryption and decryption
Securely sending emails without Microsoft Outlook ®
The most frequently used mail client in the world is probably Microsoft Outlook ®. Naturally, we offer an Outlook plugin for email encryption. However, even without being a user of Microsoft Outlook ® you are able to encrypt emails with REDDCRYPT. Besides our device-independent web app we offer a standalone application for Microsoft Windows operating systems.
Just like an email client
After installing our REDDCRYPT Windows app on your computer you will be able to write and securely send encrypted emails containing sensitive information.
Visually the Windows app looks like a regular mail client. Of course, emails can be formatted, images can be inserted and attachments can be added.
Whether recipients are already REDDCRYPT users can be seen after entering their email addresses.
Encrypted with only one click
Recipients whose email addresses are marked green are already users of REDDCRYPT. In these cases there is nothing more to do. The email is encrypted automatically and the recipient can decrypt the email using one of the REDDCRYPT apps.
Recipients whose email addresses are marked yellow are not yet users of REDDCRYPT. Not to worry – you can still send them encrypted emails.
Unique passwords for new recipients
If the recipient of your email is not yet using REDDCRYPT you are still able to send him or her encrypted emails. For this you simply define a passphrase that you communicate to the recipient via SMS, call, letter etc. It is highly recommended to not send this passphrase via email but to use another medium (i.e. media disruption).
Afterwards the recipient can create a free account with his/her email address and a password of his/her choice. Upon successful authentication the recipient can see your email and decrypt it with the passphrase. This process is only necessary for the first email. After the first email no passphrase is needed as the recipient is now also a REDDCRYPT user and the encryption & decryptiom takes place automatically in the background
Decrypted with one click
When receiving an encrypted email there are two ways to read it.
The email is send as an encrypted attachment as part of an info mail to your regular inbox. After having installed the Windows app you will be able to open the attachment (containing the encrypted email) with a simple double click.
Alternatively you can, of course, simply open the Windows app and the email you received will be decrypted and readable there.
