MessageLock is an add-in for Microsoft Outlook that allows the sender to protect email messages using strong AES-256 bit encryption (exceeds HIPAA's minimum requirements, US Government approved).

To use MessageLock, just open a new email message Microsoft Outlook, and click the "Encrypt Email" button in the Outlook email toolbar.

MessageLock is virtually seamless when both sender and receiver have it installed. MessageLock will automatically decrypt inbound packets, and display the email as a regular message in your Outlook inbox. The decrypted message will be time-stamped, as proof that it was received securely.

Sending Encrypted Messages

When sending email to someone who does not have MessageLock, there are three simple options to deliver your message securely:

1. Send using zip-compatible encryption. This method requires that the user have a zip utility (such as Tugzip.com or IZarc.org) to decrypt the MessageLock file and access the contents. The recipient may already have this software, but if not, it is free to download. Using zip encryption works very well most of the time, but occassionally a firewall may block an encrypted zip file.

2. Require the use of MessageLock Decryptor. This method requires that the recipient download MessageLock Decryptor to open the .ml256 packets that MessageLock creates. The Decryptor can be hosted from your website, if you wish. After installing the Decryptor, the user simply clicks on the .ml256 file to open your message; MessageLock Decryptor will then prompt for the password. This method has proven very reliable in delivering the encrypted packetl.

3. Send a self-decrypting file. This method allows you to create a self-decrypting .exe file which when run, will prompt the recipient for the password. The user does not require any special software. The executable file is delivered in an unencrypted zip wrapper, accessible to Windows XP and Vista without a zip utility.

Whichever method is chosen, MessageLock will remember it, and apply the settings to future encrypted emails to that recipient.
