Description
The app allows you to encrypt or decrypt text with the simple and widely known Caesar cipher. If you have an caesar encrypted text with a unknown key, the application can decrypt the text for you! This might be useful for riddles or geocaching. Furthermore, the algorithm is visualized with an interactive cipher disk which you can export and print to craft your own paper cipher disk.
The cipher is named after the famous roman dictator Gaius Julius Caesar. It works with a simple substitution mechanism where each letter is replaced by another letter in the alphabet. For example with a right shift of 5 an "A" is replaced with an "F".

Comments on Caesar cipher - De-/Encryption for Android
★★★★☆Inky· Apr 25, 2025
I wish I could customize the ciphers more like the ceasar ciper letter shiftier thingy literally on Google search. It allows me to add two ceasar cipers at once but still ill use this

Love it because it still can be applied in certain circles. Would be nice if one could "name" the alphabets. Drawback there isn't a way to DELETE a custom alphabet. What about Share button for the Encoded output?
★★★★★JanovicHero RFM· Apr 3, 2021
Its is a good app. Because it's good when you as receiver got an unknown Key for Chiper text. It can auto find plain text base on Key (shift 1-25). Btw, I hope there is available app for Viginere code too where's it can auto decrypt key or make it 2 in 1 in this app.I will recommended this app to my friends...TQ developer...

Opened and had zero instructions. Zero help/instruction files. No obvious way to select and encrypt desired files. Deleted this feeling like I very much did the right thing.
