A portable application and powerful file compression utility that provides 256-bit AES encryption.
Pros & Cons:
7-Zip Portable is a powerful file compression utility that provides 256-bit AES encryption for *.7z and *.zip formats.
It's very easy to use, but has a short, steep learning ramp. Be aware that if you add an unencrypted to a encrypted 7-Zip archive, the unencrypted file must be shredded, not just deleted. Otherwise it will be available to anyone who has access to your computer.
Do not edit and save files directly in the archive either as they will not be encrypted.
