Some software suites have encryption tools built in for you to use. Microsoft has included encryption tools in the Info tab under the File menu since Office 2010. Adobe Acrobat Pro X includes the option under the Protect section in the Tools tab. In both cases, the file is encrypted and decrypted with a password, so make sure to select a very complicated one, and keep it separate from the file itself.
If you frequently send Zip files and don’t want to make recipients jump through hoops to generate a MiniLock public key or install special software, the 7-Zip file archiving utility may be for you. While its primary purpose is to compress and decompress large files and folders, it can also turn individual files into encrypted volumes using 256-bit AES encryption. When creating the archive, assign a password, and the utility will take care of the encryption. The recipient only needs to know the password to decrypt the volume. It’s the easiest way to use encryption without confusing people who may not feel comfortable creating public keys or don’t want to sign up for yet another service.
User adoption is key
Encryption helps keep our communications with our banks private from criminals interested in stealing our money. It keeps our health records safe when they are transferred from one server to another. It prevents others from spying our credit card numbers when we are shopping online. Yet governments will continue to push back against encryption technologies in pursuit of backdoors by pointing to criminal activity and communications online -- regardless of whether they were conducted using encrypted channels.
What governments and law enforcement agencies are missing is that encryption benefits everyone, not only terrorists and criminals. Even governments rely on encryption to keep their secrets, after all.
While encryption technologies advance, becoming easier to implement, and default standards for encryption begin to fall into place, the best thing we can do is begin to use encryption tools in our daily computing lives. Too much depends on our right to privacy and security not to.
