Decipher - Code and Cipher Kit

Decipher is a brand new tablet-optimised tool to encrypt and decrypt text in a variety of ciphers.
Currently Includes:
- Atbash
- Binary
- Octal
- Hex
- Caesar Shift
- Keyword Cipher
- Substitution Cipher
- Vigenère Cipher
- Beaufort Cipher
- Hill CipherAnd more on the way! (Please email me with which ciphers you want to see!)

Also automatically cracks Caesar, Vigenere, Beaufort, Keyword and Substitution ciphers! (Note: cracking is done statistically, and so needs a large amount of ciphertext to be reliable)Plus Frequency Analysis tools!

Also can display information about the ciphers from Wikipedia or practicalcryptography.com, making Decipher a great educational tool as well.

Choose between light and dark themes!

I use this app to prank my friends and they think I'm talking gibberish when in reality I'm using ciphers it's hilarious

This app is simple to use and one has the option to use the most popular classical ciphers available. With the one time pad key system the ciphers in this app is as unbreakable as anything one can use. This even has bi-gram and tri-gram counter. Useful in cryptanalysis. I love this app.

Hexadecimal decoder does not work at all

Looks fine, but there's nut much choice. Eg, can't do base64

Good at ciphers and deciphering.

This app is a piece of s*** it does not decode anything i even used the code it made and it could not decipher it

Love it

Great UI and clean easy to understand. I also like that it will give you a wikipedia article explaining each cipher. Tablet optimized, what more can one ask for.

Great for quickly encoding/decoding messages in a variety of ciphers, and the interface is very elegant and intuitive. The frequency analysis tool is a nice touch, and also shows digrams and trigrams - which other apps don't. Would be nice to have some stronger ciphers (AES perhaps?) and am looking forward to the cipher cracking update - but in all other regards this is in my opinion the best cipher app on the market at the moment. Nice job!

pretty much just as useless as all of the other decipher and encode apps in the Android store.

Dev posted on reddit looking for feedback and implemented much of feature requests in the comments. Awesome! Keep up the good work.
