Portable Crypto

Portable Crypto is a lightweight and portable application that enables users to encode messages via the Blowfish CBC algorithm. You can use it whenever you want to send an encrypted message to friends over the Internet (provided that they have this tool as well), in order to prevent unauthorized users from viewing sensitive information.

Since there is no setup pack included, you can extract the program files to any location on the disk and click the executable to run.

Another possibility is to save Portable Crypto to a USB flash disk or other removable device, in order to run it on any machine without prior installers.

What's worth mentioning is that the tool does not add new entries to the Windows registry, Start menu or other area of the computer, so a simple file deletion is enough to remove all traces.

The interface of the app is based on a single window, where you can write text and enter a key, in order to encrypt the messages successfully. From this point on, you can copy the encoded data to the Clipboard and send it online. Another party shall be able to decrypt the message if they know the key, as Portable Crypto also provides a decryption feature.

The tool barely uses CPU and RAM, so it doesn't burden system performance. It has a good response time and performs an encryption/decryption task rapidly and error-free. Although it has not been updated for a long time, Portable Crypto works smoothly on newer OS platforms.
