Ciphriend
Interactive cipher encoding and decoding tool with a real-time visualizer for classical cipher operations.
Overview
Ciphriend is an interactive playground for classical ciphers. Type a message and watch substitutions, transpositions, and rotations transform it step by step — encoding and decoding rendered as live animation rather than static output.
Key Features
- Real-time encoder and decoder for multiple classical cipher families
- Frame-by-frame animation of cipher operations
- Frequency analysis tooling for unknown ciphertext
