Introduction to mkryptor


mkryptor is like a courier, only faster and more secure. mkryptor safely picks up your emails and securely delivers them to your recipients.

How does it happen? First, mkryptor receives your normal unsecured emails from your usual email client or server. It wraps your email into a secure envelope, which only the intended recipients can open. Then, mkryptor delivers this now secured email directly to the designated recipients.

You wouldn’t send a letter to a client without using an envelope, so why do it with your email?


mkryptor works on all common computer systems, like Microsoft Windows and Mac OS. mkryptor also works with all popular mobile devices, such as iPhone, Android and BlackBerry.


With mkryptor your recipients don’t need to install any special software on their computers or devices. You don't even need to tell your recipients to expect a secure mail. And you certainly don't need to arrange for training to open it.


Good news: you don't have to send your recipients any passwords. You don’t have to ask to register on any websites. No need to change anything on their computers or devices.

mkryptor works straight away with any email client - and it’s so simple you must try it.


More good news: sending a secure email doesn’t require installing any special software on the recipient’s computers or devices.

mkryptor Business+ Edition

mkryptor Business+ Edition is our secure email processing engine which can be installed on your own servers. This allows you much more control over the functionality and appearance of mkryptor.

The Business+ Edition of mkryptor is packed with security features to ensure all your emails are fully secured. It also comes with a large-scale database used for remembering the information for encrypting messages for each of your recipients. This means you don't have to keep supplying this information each time you send a message.

This database is shared with everyone in your organisation using mkryptor and allows others to send secure messages to the same recipients each time using the same shared encryption information. This makes sending and receiving secured messages even easier for you, your colleagues and your customers.

Your messages will also be signed with up to three different digital signatures proving the authenticity of the message to your recipients.

In addition to sending secure messages, you can also receive instant and secure replies from your recipients.

mkryptor Business+ Edition also allows you to send secure messages to thousands of recipients using electronic mail-merge. Here you create a single email template and a single file of recipient data such as an Excel spreadsheet. Then when you send this template and file in a message to mkryptor it will generate a customised message for each recipient based on the data in the spreadsheet. mkryptor with then encrypt, digitally sign and deliver each secure message to each recipient.

You can download mkryptor now from our downloads page and be fully operational within only a few minutes using a fully functional free 14 day licence.
