Kryptor

Command-line applications are usually preferred by experienced users since they can greatly speed up whatever operation they want to perform.

The same applies to Kryptor, a cross-platform tool especially created for encrypting and decrypting files.

It goes without saying that you first need to open the Command Prompt window to be able to enjoy the functions of Kryptor. To get a better idea of the strengths of this app, you can just type --help and a list of all supported actions is generated.

There are some examples that can help you get familiarized with the correct syntax.

Due to Kryptor, you can start encrypting files and folders using the password you prefer - alternatively, you can leave it to the utility to create a passcode for you or you can specify a private or a public key instead (you even have the possibility to recover your public key from your private one).

Decrypting your data can be done just as easily. You can choose to obfuscate the file names to protect your privacy or you can even overwrite the source files to make sure nobody can get their hands on the unencrypted records.

Moreover, a signature can be obtained and a comment can be added to this signature as well. If you want to, you can verify the signature or choose one from your local files. Another operation you can perform is to sign large files by prehashing them.

Kryptor can help you perform numerous encryption-related tasks even though it does not come with a graphical user interface (GUI) per se. Even if you are not particularly familiarized with command-line syntax, you can experiment with the commands for a while using test files and start working on your real data once you are confident in your abilities.
