project for an8x (integrate and fix)

Hi an8x, could you please check if you can help us integrate the file encryption module to made File encryption ofption for our website? We have a Javascript module that can encrypt/decrypt file with a custom passphrase and we want to integrate this module into our website to let user to encrypt their files before upload to our website. We want to make a "Encryption Upload" button, when user click on this button we will let they choose to encrypt file with their user password (plain password) or encrypt with an custom input passphrase (see image below) And when user download an encrypted file, we will ask them input their passphrase to decrypt (if they use custom passphrase) or use their password to decrypt the files. [the password we said here is the plain password, which is the password plaintext that typing by user everytime they sign in, not the hasing password that we store in the database]
