MxCrypt is a platform for encrypting online communications. It aims to protect your email from prying eyes while still maintaining the convenience of your favorite email client. With MxCrypt, you can ensure that only you and your recipients can read your messages, with no one in between.

One of the key features of MxCrypt is the ability to set an expiry date on your messages. This means that after a specified time, the messages become unreadable, adding an extra layer of security to your communication. Additionally, you can also set a number of 'opens' for your messages. Once the message has been read the specified number of times, it becomes unreadable, further protecting your privacy.

MxCrypt also provides the option to revoke a message at any time. This renders the message unreadable by any recipients, giving you control over your communication even after it has been sent. Another notable feature of MxCrypt is the ability to encrypt attachments of any size, ensuring that your files are also protected.

It is important to note that currently, MxCrypt only supports the Gmail web client. However, with its easy and secure email encryption capabilities, MxCrypt is a valuable tool for those looking to enhance the privacy and security of their online communications.
