Free for everyone: web app
Device-independent access from anywhere in the world
With the web app you can access your encrypted emails anytime from anywhere in the world no matter the device you are using. You only need your email address and your password for authentication. Afterwards, REDDCRYPT automatically encrypts your emails before sending so that your emails and their contents remain private.
Easy to use for everyone
The recipient creates a free account with his email address and a password of his/her choice. After successful authentication the recipient is able to see the email sent by you.
This email is accessible online for a duration of 30 days. Additionally, the email has been transferred to the user’s regular inbox and can be decrypted in any REDDCRYPT app even after 30 days.
Decryption in the browser
If the recipient already has a REDDCRYPT account they can read the email immediately after opening their app.
If this is their first time receiving an encrypted REDDCRYPT email they will be prompted to enter the defined passphrase after clicking on the mail.
In order to securely communicate the passphrase we recommend a media disruption, i.e. communicating the passphrase via SMS, phone call or letter to the recipient. In any case, the passphrase should not be communicated via email.
Reading emails in the browser
After successfully entering the passphrase the recipient gains access to the emails and potential attachments. If desired, he can reply to the email or forward it to third parties. If the email is forwarded to someone who is not a REDDCRYPT user the definition of a new passphrase is required.
Additionally, the recipient has the option of saving emails to his device if he so wishes.
One time passphrase
If you reply to this email a passphrase is not required because the recipient is also a REDDCRYPT user. The recipient already has a public key available which is used for the decryption. Of course, this does not only apply for replying but also for sending new emails.
With REDDCRYPT you receive the highest possible user comfort as a passphrase is only necessary once.
