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 Cipher
And 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!

- PERMISSIONS -
INTERNET - Requires use of the internet to serve Wikipedia pages about the ciphers and to serve ads.
BILLING - Required to serve in-app purchase.

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

    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.

    Started sending encrypted messages with a couple of friends and I can tell you now that I stopped caring if people looked into my messages, no one has a clue as to what they're saying. I guess that would have to be my favorite part about this app. Keep up the simple UI and more updates!

    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 cip
