Whether it's sensitive business or sensitive gossip, there are plenty oftimes when we'd prefer our email to be more secure.

The solution is to encrypt the messages and only allow their intended recipient to decrypt them at the other end. This is where A-Lock comes in. Simply type your message as normal in your email program, then click the A-Lock icon in the task tray in order to encrypt it.

If you receive encrypted messages, follow the same process.

A-Lock cleverly displays the decrypted message in a separate window, leaving the one in your inbox securely scrambled. There's also a lockable password book.

Upgrade to the Pro version for $29 and get these extra features:

• Stronger passwords - up to 56 character (448-bit) passwords.
• Key Exchange - automatically generate random alpha/numeric character passwords.
