When you are dealing with sensitive information, you might want multiple methods of keeping it safe. One layer of security you can apply is to encrypt the files or emails in question. With a program like CryptoMite, this is an option available to all levels of users. The program makes the process simple, integrates perfectly with Windows and has various levels of options, making sure that beginners aren't overwhelmed and pros aren't bored.
The CryptoMite interface is very much of the functional description - in other words, it's fairly ugly. The program also works from the context menu, allowing you to directly encrypt and decrypt files and folders. The main CryptoMite interface lets you set the configuration of the commands executed from the context menu, gives you access to email options and a small selection of bonus functions, such as the ability to hide drives and directory and set passwords for .EXE files. Just remember that you'll need CryptoMite installed on the computer that you want to use to view the information.
CryptoMite's best feature is the variety of encryption options available - AES, Twofish and SCOP being just some - and the options it provides for wiping your information post-encryption and setting passwords for the encrypted files. It also has a comprehensive email wizard for sending encrypted mails and attachments. Add all these features to a program that is light on resources, easy to use and completely integrated into Windows, and CryptoMite is definitely a winner.
Appearances aside, CryptoMite is a great file encryption program.
