LHN's CryptoText

Even plain text files can contain confidential strings, and there's no actual method of securing them by default other than to add inside a password-protected archive. On the other hand, some specialized applications like LHN's CryptoText can help as a personal text editor and encryptor at the same time.

One of the application's main advantages is that you can carry it around on a thumb drive to use on other computers, because it doesn't require installation in order to function. Besides the great deal of flexibility it provides, it also keeps the target computer clean, because it leaves no traces, and doesn't make any changes to registry entries to enable functionality.

You work with plain TXT files by default. You're able to load and save under this format. However, encrypted files are saved as HeavMem files you can later on load and process. A file you want to encrypt or decrypt can be dropped over the main window, but you can also paste text or start writing it here.

Encryption is done in a couple of modes. The simple one uses a built-in algorithm in order to make text unreadable, while the reverse reveals original strings. For the second type to function a key file first needs to be created. There's a default function to take care of this issue, and it's best to create a backup to be able to retrieve files later on.

The application also comes with a set of extra tools. These also target encrypted files, and can help cut, reconstruct, and extract text from encrypted files without decrypting them first. There's no password involved in the encryption process, with the whole algorithm relying on the key file you create.

LHN's CryptoText is a secure way of handling text files on the long run. Although it only works with plain text files, it comes with a fast, powerful encryption method you can even carry around at all times. Just be sure to keep the key file safe no matter what, otherwise you can't decrypt protected documents.
