A Rust workspace containing implementations of various cipher algorithms, along with a command-line interface (CLI) and a web interface to interact with them.

Features

AES Implementation: AES-128 block cipher and CBC mode
DES Implementation: DES block cipher
Command-Line Interface: Encrypt and decrypt messages or files using the supported ciphers
Web Interface: Browser-based encryption with file upload, drag-and-drop, and random key/IV generation

Workspace Structure

The cipher-workshop workspace is organized into the following crates:

aes: Implementation of the AES cipher (block cipher and CBC mode)
cipher-core: Core traits and types for ciphers
cipher-factory: A factory for creating cipher contexts
crypt: A command-line interface for the ciphers
des: Implementation of the DES cipher
web: A web interface built with Leptos

Getting Started

Prerequisites

Rust
cargo-leptos (for the web interface)
Node.js (for end-to-end testing)

Building the Project

Clone the repository and build the workspace:

git clone https://github.com/kristofers-solo/cipher-workshop.git
cd cipher-workshop
cargo build

Usage

CLI

The CLI allows you to encrypt and decrypt messages or files using the supported ciphers.

AES (block mode)

# Encrypt a message
cargo run --bin crypt -- encrypt -a aes -k 0x2B7E151628AED2A6ABF7158809CF4F3C "Hello World"

# Decrypt a message
cargo run --bin crypt -- decrypt -a aes -k 0x2B7E151628AED2A6ABF7158809CF4F3C 0x...

AES-CBC (with IV)

# Encrypt a file
cargo run --bin crypt -- encrypt -a aes-cbc -k 0x2B7E151628AED2A6ABF7158809CF4F3C --iv 0x000102030405060708090A0B0C0D0E0F -i input.txt -o output.enc

# Decrypt a file
cargo run --bin crypt -- decrypt -a aes-cbc -k 0x2B7E151628AED2A6ABF7158809CF4F3C --iv 0x000102030405060708090A0B0C0D0E0F -i output.enc -o decrypted.txt

DES

# Encrypt a message
cargo run --bin crypt -- encrypt -a des -k 0x133457799BBCDFF1 "Hello"

# Decrypt a message
cargo run --bin crypt -- decrypt -a des -k 0x133457799BBCDFF1 0x...

Web Interface

The web interface provides a user-friendly way to interact with the ciphers, available at: https://cryptography.kristofers.xyz/

Features:

DES, AES, and AES-CBC encryption/decryption
Random key and IV generation using Web Crypto API
File upload with drag-and-drop support
File download for encrypted/decrypted output
Multiple output formats: Hex, Binary, Octal, Text

To run the web interface locally:

cd web
cargo leptos watch
