CipherLock

Brutalist Cryptography Hub

CipherLock is a high-contrast, zero-tracking interface for classic cryptography and data encoding. No databases. No server processing. Everything is 100% client-side.

Core Components

• The Hub: A real-time environment for encryption and decryption.
• The Academy: A dedicated space for historical and technical education on algorithms.
• Client-First: All data transformations happen locally in the browser.
• Brutalist UI: Monochrome, high-contrast design focused on speed and clarity.

Supported Algorithms

Cryptography (Key Required)

• Caesar: Shift-based substitution cipher.
• Vigenère: Keyword-based polyalphabetic encryption.
• Atbash: Fixed alphabet reversal.
• Rail Fence: Zig-zag transposition logic.

Encoding (Standardized Format)

• Morse: Classic dots and dashes.
• Base64: Web-standard binary-to-text representation.
• Hexadecimal: Byte-level base-16 machine language.

Technical Stack

• Framework: React 18 + Vite.
• Logic: Decoupled TypeScript modules for all algorithms in src/utils/ciphers/.
• Styling: Tailwind CSS.
• Primitives: Radix UI + Shadcn.
• Testing: Vitest + React Testing Library.
