In depth

A closer look at Puffer

Puffer is a versatile and efficient Windows utility that allows you to protect your sensitive data thanks to its 256-AES symmetric encryption algorithm. It also comes with support for 2048-bit Diffie-Hellman public keys, 2048-bit q-NEW digital signatures, and SHA-256 authentication.In short, it makes it possible for you to create zip-style archives (all while keeping the internal directory format and hierarchy untouched), as well as self-decrypting archives to users who don't have this particular app installed. As a bonus, it also provides you with the possibility of securely exchanging emails with other Puffers users.

Packs a surprising mix of productivity and encryption-related bells and whistles

Since this app is all about confidentiality and keeping data protected, besides its noteworthy set of encryption features, the application also bundles a simplistic wiper or file shredder.The app's feature set does not end here, as it also packs a built-in text editor and even a clipboard viewer, to make it a bit easier for you to handle sensitive data. When it comes to handling its own internal data, Puffer also sports a very handy archive manager and a key ring manager.

Well-equipped and still very much useful general purpose encryption utility for your computer

The application is incredibly lightweight and doesn't have any sort of unusual or special requirements, and, to get it up and running, simply let yourself be guided by the typical, step-by-step, installation wizard.To conclude, Puffer is definitely a very interesting and well-thought-out piece of software. It's true that it does look a bit outdated, unsurprisingly, considering it's a very old app, but it has enough compelling features to keep it relevant even by today's standards.
