Silver Key is a file encryption program that encrypts files or folders and produces encrypted parcels, which can be safely sent over the Internet. Silver Key parcels are self-extracting and don’t require the recipient to have any cryptographic software installed. You can also specify additional action to be performed during decryption, such as creating a shortcut to the decrypted file, or opening the file using the associated application.

If you need to send sensitive data over the Internet you should encrypt it first. But what about the other side? The recipient will probably not like the idea of buying and learning some software just to decrypt your file. No problem here if you are using Silver Key.
