## Description

w3mypq provides a privacy-focused file encryption and sharing tool for WordPress.
Files are encrypted in the user’s browser before upload using ML-KEM and AES-GCM.

The plugin combines modern cryptographic standards with low-level binary packing,
thread isolation, and forensic memory management. Its low-overhead, browser-based
processing supports secure, post-quantum (PQ) file sharing between users.

#### Features

 * Uses ML-KEM 1024 for post-quantum key encapsulation.
 * Supports ML-DSA 87 signatures for sender verification.
 * Files are encrypted locally in the browser before upload.
 * Uses AES-GCM-256 for file encryption.
 * Uses SHA-512 for integrity verification.
 * Supports sharing files with one or more recipients.
 * Recipients decrypt files locally using their own private keys.
 * Includes a guest mode for local encryption and decryption without storing files
   on the server.
 * Designed around current NIST post-quantum cryptography standards.

#### Admin Options

 * Settings page managing maximum attachment sizes, user role permissions access,
   and dynamic file retention limits. WP admin -> Settings -> w3mypq

## Installation

 1. Upload the plugin folder to the `/wp-content/plugins/` directory, or install it
    through the WordPress Plugins screen.
 2. Activate the plugin through the Plugins menu in WordPress.
 3. Add the shortcode `[w3mypq_short]` to a page or post.
 4. Open the page and use the interface to generate keys, encrypt files, and share 
    them with recipients.

#### Customization

To preserve customizations during updates:

 1. Copy the `w3mypq-custom` folder from the plugin directory into `/wp-content/plugins/`.
 2. Edit:

 * `w3mypq.css`
 * `w3mypq_body.html`
    1. The plugin automatically loads these files when present.
    2. If the custom files are not found, the default plugin files are used.

## FAQ

### What does this plugin do?

The plugin allows users to encrypt files locally in their browser before sharing
or storing them.

It supports post-quantum key encapsulation using ML-KEM and digital signatures using
ML-DSA. Encrypted files can be shared with recipients who decrypt them locally using
their own private keys.

### Does the server store my private keys?

No.

Private keys are generated locally in the user’s browser and should be stored securely
by the user.

The server only stores information necessary for sharing encrypted content, such
as public keys and encrypted files.

### What are ML-KEM and ML-DSA?

ML-KEM and ML-DSA are NIST-standardized post-quantum cryptographic algorithms.

ML-KEM is used for secure key exchange and ML-DSA is used for digital signatures
and sender verification.

### What is guest mode?

Guest mode allows visitors to perform encryption and decryption locally without 
creating an account.

Files do not need to be uploaded to the server when using guest mode.

### Can I share files with multiple recipients?

Yes.

Registered users can encrypt files for one or more recipients. Recipients receive
access information and can decrypt files locally using their corresponding private
keys.

### How is the Noble library used?

The plugin includes a compiled version of the Noble post-quantum cryptography library.

The plugin’s `/noble` directory contains additional information about the library
and its build process.
