Cryption

In-Browser AES File Encryption with Data Integrity Check

Website

Introduction

Cryption is an open-source tool that encrypts and decrypts your data in the browser.

It does not upload data to any cloud.

It checks the file integrity, making it impossible to manipulate data without the correct password.

You can also give hints in order to remeber your password.

If you want to, you could download Cryption and use it fully functional offline on your computer.

Usage

Usage Information

To use Cryption as it was intentioned, I advice you to use Firefox. Both Chrome and Safari will crash when files get big (>25 MB), while Firefox managed to encrypt and decrypt files larger then 100 MB. It was also the fastest, but nonetheless, every browser should work

If you want to upload a directory, consider zipping it before uploading, since JavaScript cannot handle directory uploads. You can, however, upload multiple files, which Cryption then bundles to a zip-archive automatically.

Prerequisites

• Node.js >= 10
• npm >= 5
