CryptoHeaven

CryptoHeaven is a comprehensive and intuitive email client that enables you to encrypt messages before sending them to other people, in order to prevent unauthorized parties from getting ahold of your private information.

At startup, it's necessary to sign up for an account (for free) using an existing email address that will be further applied to the sender, as well as to specify the password recovery method. The interface is represented by a large window with a neatly organized look, where you can switch to another identity easily.

It's possible to import an address book and create a shared and secure space with any contact, or transfer files and folders to an online account for safekeeping.

When creating new messages, you can enable a spellchecker, attach files, and record audio notes. Folder properties and sharing settings can be managed anytime. You can set the tool to automatically purge files to limit the number of records.

The software application also puts a search function at your disposal that lets you search even in message content. What's more, you can handpick the exact columns to display while leaving out the rest, create and administer a list of allowed senders, trace folder access, modify account options (including signatures and user permissions), as well as customize the toolbar and menus.

The program had minimal impact on computer performance in our tests, thanks to the fact that it needed low CPU and RAM to work properly. It didn't hang or crash. Taking into account its resourceful options and configuration settings, CryptoHeaven proves to be a reliable app for securely sending emails by encrypting them.
