Hi, I am a solo developer and I build file encryption which is entirely browser based meaning the file is not stored in any server.

I use AES-256-GCM (uses PBKDF2-SHA256 with over 150,000 iterations to securely derive a 256-bit encryption key from the password and a unique random salt

The entire method realise entirely on the browser native web encrypt API this means it is a 100% client side zero knowledge method were no file or password ever leave your device with no file size limitations

Can you suggest me any improvement to make it very useful and solve the problem
