# CipherChronicle
> Front-only encryption-puzzle platform. Documents 80+ historical and modern ciphers (Caesar, Vigenère, Enigma, Zodiac, Babylonian numerals…) and ships an in-browser workshop to encrypt or decrypt by chaining methods. French-first, English parity. Static SSG (Astro), no backend, all crypto runs client-side.
## Workshop
- [Atelier de chiffrement (FR)](https://www.cipherchronicle.com/fr/chiffrer): compose a chain of ciphers and run cleartext through it; deep-linkable via `?cipher=<id>&value=<text>`.
- [Atelier de déchiffrement (FR)](https://www.cipherchronicle.com/fr/dechiffrer): mirror page that reverses the chain.
- [Encryption workshop (EN)](https://www.cipherchronicle.com/en/encrypt)
- [Decryption workshop (EN)](https://www.cipherchronicle.com/en/decrypt)
## Cipher methods — French
### Implémentées (163)
- [Chiffre de César](https://www.cipherchronicle.com/fr/methodes/caesar): Décalage fixe de l'alphabet. Le grand classique, simple à comprendre, simple à casser.
- [ROT-13](https://www.cipherchronicle.com/fr/methodes/rot-13): Cas particulier de César (décalage 13, involutif).
- [Atbash](https://www.cipherchronicle.com/fr/methodes/atbash): Renversement complet de l'alphabet. A ↔ Z, B ↔ Y.
- [Chiffre de Vigenère](https://www.cipherchronicle.com/fr/methodes/vigenere): Un César dont la clé change à chaque lettre. Longtemps jugé incassable.
- [ROT générique](https://www.cipherchronicle.com/fr/methodes/rot): La famille mère des décalages : ROT-N pour tout N entier. ROT-13 et ROT-47 sont les cas iconiques.
- [Substitution monoalphabétique](https://www.cipherchronicle.com/fr/methodes/substitution): Une permutation libre de l'alphabet. 26! combinaisons — mais la fréquence trahit.
- [Chiffre affine](https://www.cipherchronicle.com/fr/methodes/affine): Chaque lettre subit une formule ax + b mod 26. Un cousin algébrique de César.
- [Rail Fence (zig-zag)](https://www.cipherchronicle.com/fr/methodes/rail-fence): Transposition en zigzag sur plusieurs rails. Simple, visuel, pédagogique.
- [Carré de César](https://www.cipherchronicle.com/fr/methodes/caesar-square): Texte écrit en lignes dans un carré, relu par colonnes. Transposition la plus minimale.
- [Chiffre de Bacon](https://www.cipherchronicle.com/fr/methodes/bacon): Chaque lettre → séquence de 5 symboles A/B. Précurseur du binaire.
- [Code Morse](https://www.cipherchronicle.com/fr/methodes/morse): Points et tirets. Né du télégraphe, toujours vivant en radio.
- [Chiffre A1Z26 (rang alphabétique)](https://www.cipherchronicle.com/fr/methodes/a1z26): A = 1, B = 2, …, Z = 26. Le code lettre-chiffre le plus intuitif pour débuter.
- [Carré de Polybe](https://www.cipherchronicle.com/fr/methodes/polybius): Chaque lettre → paire de coordonnées dans une grille 5×5.
- [Chiffre de Beaufort](https://www.cipherchronicle.com/fr/methodes/beaufort): Un Vigenère involutif : chiffrer = déchiffrer.
- [Scytale (bâton spartiate)](https://www.cipherchronicle.com/fr/methodes/scytale): Le cylindre spartiate
