Caesar(圖1)-速報App

It supplies for now :

Caesar(圖2)-速報App

- Caesar cipher (Cryptanalysis included, with the possibility to use a convenient cipher wheel),

Caesar(圖3)-速報App

- Affine cipher (Cryptanalysis included),

Caesar(圖4)-速報App

- Monoalphabetic substitution cipher with keyword or user-defined alphabet (Cryptanalysis included ***),

Caesar(圖5)-速報App

- Hill cipher (Matrix sizes : 2x2, 3x3 and 4x4) with the possibility to manage 3 matrices,

Caesar(圖6)-速報App

- Vigenère/Beaufort cipher with 2 variants (Cryptanalysis included ***),

Caesar(圖7)-速報App

- "Vigenère + keyword" cipher. It's possible to save the encoding tables in CSV format in the folder CESAR of the device's storage. The keyword permutes the columns of original Trithemius-Ciphertable into another latin quarter.

Caesar(圖8)-速報App

- "Generalized Vigenère" cipher. It's possible to save and load the encoding/decoding tables in CSV format or the keywords to a text file (protected by a Vigenère key) in the folder CESAR of the device's storage. Every thinkable Encryption-Table (26x26) can be defined by the user (about 5.6 * 10 ^ 691 possibilities !).

You can send a cipher message via SMS or email. You can also call the application when a text message is shared and choose the encoding method.

*** The N-grams for those breakers were downloaded from this very interesting site about cryptography : http://practicalcryptography.com/. Texts in english, french, german, spanish, italian and swedish are concerned.
