What is this?

It's a simple script that can be used to quickly encrypt/decrypt text contents and files using a passphrase. It is quite fast and secure, and it uses AES-256-GCM encryption.

Your content, files or passphrase are never sent to any server, everything is done in your browser locally, using WebCrypto API.

You can use it to encrypt text content or files, and then send it to someone else, and they can decrypt it using the same passphrase. You can also use it to encrypt your data, upload it to any cloud storage service, then download it later and decrypt it.

Please note that only data encrypted using this script can be decrypted using it.
