Why encrypt?

Why encrypt your emails?

Whether you realise it or not emails are like postcards.

Just as a postcard can be intercepted and read as it's being sent through the postal network... so can an email. They can even be edited.

Keep your email address

Personal email addresses are….well….personal! They are part of your identity and online self. At Jumble we believe that you shouldn’t need to create another email account just because you want to secure your emails so we’ve designed Jumble to integrate with your existing Gmail account.

Zero knowledge provider

Jumble never hosts your email data and so we have no access to it. Jumble also has no access to unencrypted private key data. Likewise the email provider has no access to the keys so once the emails are encrypted they can only ever be decrypted and read by the sender and recipient.

Unlimited email encryption

Encrypt as many emails as you want with Jumble for free – no catch!

Unlimited email decryption

Decrypt as many emails as you want with Jumble for free – no catch!

AES as standard

Jumble uses standard encryption algorithms that have been published and peer reviewed over many years. Specifically, we use 256-bit AES keys to encrypt the email data and then use a 2048-bit RSA public key to encrypt the AES key. In fact we use 2 different sets of encryption keys for each email you send:

  • 1. A random single-use AES key is created for each email sent; this key is used to encrypt the actual email

  • 2. A set of RSA keys, called a key-pair, is uniquely associated with your email address and these keys secure the single-use AES key. Jumble generates a new RSA key-pair for a given email address when it’s not already available from our API but only releases the private section of the key-pair to someone who can prove they own the email address linked with the key-pair.

Simplicity

Jumble was designed so that it could be used without any knowledge of data security, encryption or encryption keys.

Once you install Jumble you’ll notice some subtle changes to your email account – you’ll have a new button “Secure send” in your compose window.

Also, you can email anyone securely with Jumble – the recipient does not need to be a Jumble user for you to send an email encrypted with Jumble. Once they receive the email they will need to register with Jumble to decrypt for FREE – simple!

How does it work? (... the science bit)

Let’s take a look at Alice; she wants to send Bob a secure email and has come to Jumble for help.

When Alice registers with Jumble we create a special set of encryption keys and hold them for her. This allows her to login from any device or location while ensuring that her encryption keys are always available; this means she can access her emails on the go, from mobile devices, anywhere!

We use a special type of cryptography called Public Key cryptography; this means that the key we generated for Alice, let’s call is KEY-A, is actually composed of two parts; one we keep private just for Alice (this is used to decrypt messages sent to her), and a public one that we give to anyone who wants to send Alice an encrypted email.

Alice’s Jumble password is the master key for her encrypted emails. When she sends an encrypted email with Jumble we generate a random encryption key, let's call this one KEY-B. We then use Alice’s public KEY-A to encrypt KEY-B and include the encrypted version of KEY-B in the email and send it to the recipients.

This means that when Bob receives an email from Alice he can use his private KEY-A to access the message. And because Jumble always has the keys ready and waiting for Bob, he can access his emails anywhere, anytime, on desktop, mobile, tablet and email clients.

FAQ - Frequently Asked Questions

Next Generation Email Security! Jumble is a simple email encryption and data privacy solution. It integrates seamlessly on top of MS Outlook and Google Apps so you don't need to change how you work, just sign-up and install the add-in for MS Outlook or the Google Chrome extension to get next generation email security instantly.
Most people only protect their emails while they are in transit (i.e. being sent from your internet browser to the recipient’s browser). However, emails live forever and all the data should be protected at all times. The only way to do this is to use end-to-end encryption but it’s usually too technical or time-consuming to be practical. Jumble makes it simple and fast – it takes the pain out of end-to-end encryption.
In short, Jumble is a tool that allows for seamless and secure email encryption with almost no effort. Jumble is different from existing email encryption products insofar as you don't have to be already signed-up with Jumble to start receiving encrypting emails.

Additionally, Jumble works with your existing email address so no need to create a new email account.
Jumble is free for all personal users. It is important that security can be available without paying anything to anyone. As a personal user, Jumble will remain free.

Paid versions are for companies and individuals looking for extra security. Paid versions allow companies to use Jumble encryption with the companies' email domains and also access the software extensions to use Jumble with MS Outlook and numerous other email clients. Additionally, paid versions offer a rich business features such as eAudit support and 2-factor authentication.
Encryption is a way to enhance the security of a message by Jumbling the contents so that it can be read only by someone who has the right encryption key to un-Jumble it.
Today we support MS Outlook for Windows desktop, web-based Google Apps for Business & Gmail and iOS and we're working hard to bring more platform coverage to our users as soon as possible; we plan to launch Jumble support for Office365 and Android imminently with Yahoo Mail, Hotmail and Outlook.com shortly after; keep an eye on our Supported Platforms page for more info.
Jumble is self-funded and has no agreements or obligations to share data with any third party. Simply put: we believe everyone should have access to privacy and secure email and that’s why Jumble will always be free for individuals.
