About this app

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.

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.
