dead-sea-cipher

A browser-based cryptographic history demo for the crypto-compare portfolio. Walks the full arc of cryptographic history — from Atbash (~600 BCE) through AES-256-GCM (2001 CE).

Historical & Classical Ciphers

Field	Value
Coverage	Atbash → Caesar → Vigenère → OTP → AES-256-GCM
Time span	~600 BCE to 2001 CE
Scripture connection	Jeremiah 25:26, 51:1, 51:41
Live attacks	Caesar brute force, Kasiski, OTP key reuse, AES tamper detection
Educational focus	Why each cipher failed; what the next fixed

Quick Start
