Protecting documents with 3rdparty encryption

If you do not use or intend to use Office XP in the near future, there are some third-party encryption alternatives that you can use to protect your documents at home on the computer, or out in the internet if you need to email sensitive information to client, for example.

Cryptext is an extremely simple to use open source tool that password protects files with 160-bit encryption. The only caveat is that the recipient of the file must also have the Cryptext program installed in order to decrypt files encrypted by this program. Cryptext will not encrypt folders, but if you operate the program on a folder, it will encrypt each file inside with the same password. Fortunately, you can also highlight multiple files and run Cryptext on them at the same time.

To use Cryptext:

First, download and install the program. Run the program and right-click on the file or files you wish to encrypt and select 'encrypt' from the menu.

Now simply enter the password you wish to use for the file. If the file is an executable, ensure that you check the 'encrypt executable files' checkbox. Press 'ok' to encrypt the file. The file will now appear with a Cryptext icon, and cannot be opened until decrypted with Cryptext.

To decrypt files, right click on them and select 'decrypt,' then enter the password. This removes the password protection completely, and you will need to reapply it in order to protect the document.

If you are looking for more flexibility than Cryptext can offer, ABI-Coder from ABI-software is a good option. It provides many more options in a correspondingly more complex (and occasionally confusing) user interface. ABI-Coder can use 168, 256 and 448-bit encryption levels and features an explorer-like interface in which to select files for encryption and decryption.

Possibly the most attractive feature that this program offers is the ability to create self-decrypting files, meaning that the recipient of the file does not need to have a copy of ABI-Coder installed on his or her computer in order to decrypt it. They just need the correct password.
