If you're worried about the safety of your documents you should start using some encryption method to protect them.
PixelCryptor is probably one of the best options for your first steps into encryption. It enables you to protect your private documents by combining them into a package that is then encrypted with any photo of your choice.
The pixel data contained in this photo is what the program uses to protect your documents, by creating almost endless, hacker-proof combinations. And whenever you want to decrypt your documents, simply open the package with your documents and select the picture you used to encrypt it.
PixelCryptor may not offer as many security options and encryption methods as other tools, but it's very easy to use and probably the best choice for encryption newbies. On the downside, anyone who you're sending encrypted data too will need to have it installed.
PixelCryptor is a fairly basic encryption tool, mainly addressed at novice users, which uses images to encrypt confidential data.
