Kruptos 2 Professional is an easy to use how to encrypt and decrypt folders program that uses 256-bit encryption to password protect your private files and prevent them from being modified, read or even accessed without the correct password. The encrypting and decrypting process imposes a small performance overhead, but the application of such on just individual files means the overhead will rarely be noticeable on modern machines. I also use TrueCrypt for sharing between Windows and Linux machines, typically via Dropbox, as there’s no Linux version of Axcrypt. It uses GNU Privacy Guard (GPG) for content encryption and authentication, and TLS 1.2 with ephemeral keys for transport encryption. From this point forward, File History will monitor all the files and folders you have chosen and back up any files that you change. Folder Lock offers 256-bit AES on-the-fly encryption as well as syncing of encrypted files to an online storage.
Now, you can enter password to decrypt your documents or switch to the PKI mode, when another password is used to decrypt data (PKI encryption uses two different keys – for encryption and for decryption, The encryption key cannot be used for decryption and vice versa). When selecting the files to be backed up, Personal Backup only allows single files to be added at a time. The downsides are the extremely large file size and you cannot display on the web in this format.
The best time to install it is now while your PC is running, otherwise you’ll need to do so on a working Windows PC. Once done, you’ll need a blank CD/DVD or flash drive (512MB or larger – if you’re planning to recover data to this drive, go for the biggest drive you can) – the setup Password Folder wizard does the hard work. In some cases, a hybrid approach is possible, where a zip archive is used to bundle files together, and then that zip-file is encrypted with AxCrypt. Also, these encryption solutions, while viable, are less intuitive than their paid counterparts.
