If you have ever wanted a quick and easy way to send encrypted files, then MiniLock is a solution worth exploring. This is a Chrome app, so you must run the Google Chrome browser in order to use it. It is a quick, effective method for encrypting files that can only be opened by people with your designated passphrase.

Pros

File selection interface: To encrypt a file using MiniLock, all you have to do is drag it into the large surface in the middle of the app, and it is automatically encrypted. You can also select the file by browsing manually, if you prefer. The interface is easy to understand and well designed.

Perfect function: None of the files we encrypted could be opened from non-designated accounts without the passphrase. The passphrase also worked perfectly in all tests to open the encrypted files.

File name encryption: The program also automatically encrypts the file name of the file you're sending. This is very helpful and a welcome added security feature in case someone somehow intercepts the message. Any unauthorized viewers of an email containing a file encrypted by MiniLock will have no idea what they are looking at.

Cons

Confusing passphrase setup: Upon initializing the app, it asks you to set up a passphrase. When you try to put your own in, it refuses it most of the time without explanation.

Bottom Line

MiniLock is an effective, easy-to-use file encryption app. If you're a Google Chrome user, this program makes a great addition to your app toolbox.

Developer's Description

miniLock lets you encrypt any file quickly and easily, and share it securely with any friend that has a miniLock ID.

Open miniLock and enter your email and passphrase. miniLock uses your passphrase to generate a miniLock ID. You can then send your miniLock ID to friends and they will be able to encrypt files and send them to you. You can send files to your friends once you have their miniLock IDs.

miniLock IDs are very small and easy to communicate. They fit inside a tweet, business card or text message. Entering your passphrase on any computer with miniLock installed will immediately give you the same miniLock ID.

miniLock allows you to also encrypt files for yourself to decrypt later. It can encrypt files to multiple recipients, and has other features such as anonymizing both the sender and recipients of an encrypted file.

The idea behind miniLock's design is that passphrase memorized by the user, along with their email address, can act as a complete, portable basis for a persistent public key identity and provide a full substitute for other key pair models, such as having the key pair stored on disk media (the PGP approach).
