Encoding Decoding Free


Simple fast and powerful app, the best and easiest way to encrypt and decrypt any type of file and hide sensitive data you want to keep away from prying eyes. It's probably the best way to encode and decode any file type, but I'd say by far the easiest. 

You can use it to hide all your sensitive data or important documents or keep them out of sight. 

Simply select the file you want to encrypt, enter a strong password and within a short time (depending of course on the size of the file) your file will be encrypted so that no one but you or any authorized user can open it. . 

Be careful not to forget the password, otherwise you will not be able to decrypt the encrypted files. 

The new version is not compatible with older versions 1.xx, so before using the new program it is recommended to recover your old files with older versions of Encoding Decoding and re-encode them. .



Cryptomator is a simple tool for your digital self-defense. It allows you to protect your data in the cloud, yourself. With Cryptomator, the key to your data is in your hands since the application encrypts your data quickly and easily. 

Then you securely upload them to your favorite cloud service. Most cloud providers only encrypt data in transit or keep the decryption keys for themselves. 

These keys can be stolen, copied or misused. With Cryptomator only you have the key to your data. It allows you to access your files from all your devices. 

It's simple to use and integrates seamlessly between your data and the cloud. Cryptomator's technology meets the latest standards and encrypts files and filenames with AES and a 256-bit key length. 

To get started with the app, you assign a password for a folder (we call it a vault) within your cloud. 

That's all. To access the vault, simply retype the password. You will be given a virtual encrypted drive that you can move your data to (just like a USB flash drive). 

Whenever you save something to this drive, Cryptomator will automatically encrypt the data. The technology behind it is state-of-the-art and encrypts files and filenames with AES and 256-bit security encryption meaning no one can see your data.

AES Crypt


File encryption software available for various operating systems that uses the industry standard Advanced Encryption Standard (AES) to encrypt files easily and securely and does not require an expert to use. 

The only thing you need to do is right-click on a file, select AES encryption or AES Decryption, enter a password, and the program will do the rest. 

On a Mac, you can drag a file into AES Crypt and type in the required password. Using a strong 256-bit encryption algorithm, it can ensure absolute security for your most sensitive files. 

Once your file is encrypted, there's no need to worry since it's completely useless to whoever owns it without the password. 

 However, since the code we will type is of utmost importance (depending on the importance of the file or documents we want to encrypt) you should put some strong password.

Wise Folder


Free program with the help of which we can hide our data. You can use it to hide your files and folders on local partitions of hard drives or removable devices. 

The security it provides you is excellent since the data cannot be accessed by other programs or by other operating systems. The only way to access and view the data is to enter the valid password, and as you understand you should write down the password somewhere so you don't forget it. 

The application is designed for home use only and is not recommended for commercial activities of this type which naturally require even more stringent security measures. In many cases, you need to share a USB drive with others and some logical files will be read by others. 

With Wise Folder Hider, you can hide and password protect your personal files and folders on your USB stick with one click. Even if the USB is lost, your files will not be stolen. 

When you use Wise Folder Hider for the first time, you need to set a login password. Within the program, you can set a second-level password for each file, folder, USB drive. 

Anyone else cannot uninstall the program without a login password. Different from other folder hiders, when it comes to modifying a hidden file or folder, users don't need to hide it, edit it, and then hide it again. 

A single click on the 'Open' button will open the hidden file or folder to make it visible to you. You can then edit or modify it as if it hadn't been hidden. When you're done editing, close the program and the file or folder will automatically hide again, saving you extra steps.
