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 strength requirements).
To use MessageLock, just open a new email message in 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 methods you can shoose from 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.
Password Storage
MessageLock can collect and manage your passwords, both for sending and receiving encrypted files. Users can begin using it immediately, and MessageLock will gather the passwords as necessary. Access to the master password list can be protected,

What Kind of Information Should I Protect When Sending an Email?
Governments will often define specific requirements for the kind of information that must be protected.
In our every day lives, we should seek to protect even seemingly routine details or information about ourselves, our families, and our business. Information about where we've been, where we are and where we're going to be.
Here are examples of information that you should seek to keep private in an email.
  • financial reports
  • product performance and sales reports
  • word documents containing drafts or work for hire
  • any information considered embarrassing or confidential
  • any information where there is a reasonable expectation of privacy
  • credit card numbers
  • client lists
  • marketing plans
  • signed contracts
  • contract in progress
  • account statements or balances
  • expense reports
  • business negotiations
  • any discussions involving advice from or requests to a professional advisor, including your your CPA, attorney, banker, or financial advisor
  • discussions about employee performance
  • designs
  • travel plans
  • power-point slide presentations
  • login passwords
  • social security numbers
  • birth dates
  • hotel reservations
  • personal or business photos
  • computer source code
  • set appointments
  • real estate purchase negotiations
  • resumes
  • job applications
  • and much more...
MessageLock makes it easy to add password protection to an email message and/or attached files.
Just type your message, click "Encrypt" and "Send" your email.
Recipient's only need a zip utility, such as WinZip or TugZip, with AES encryption capability. That means that no single use "reader" software is required to access the contents of your encrypted message.
Using the Zip format to deliver strongly secured messages makes it practical to send and receive encrypted files. Most other email encryption solutions have been designed with larger business in mind, which can afford the burdensome infrastructure costs associated with procuring, installing, supporting and maintaining these enterprise solutions.
