FEATURES:

**Encryption**

-Use any of the sample messages or type your own message and encrypt it with Caesar or Vigenere schemas. The first schema is a simple character shift. The second one, Vigenere, is more involved since each letter can be encrypted in more than one way.

-Send your messages to your friends or family and challenge them to decrypt your secret message.

In case you are stuck, you can always break the cypher! Once you have broken the encryption you can view bar chart graphics with relevant information regarding the encrypted text.

-Liked some plain text or encrypted messages? Save them, and then open them later. You can also view, update, delete and sort all your saved messages.

-Each encryption scheme has links with relevant information of how the encryption works, its history and how you to use statistical analysis to break encryptions!SECRET MESSAGE:

**Hashing **

-Use any of your saved texts or type a new message to calculate its hash

-Text hashing supports SHA-1, SHA-256, SHA-384, SHA-512, MD5, RC4, Blowfish, AES algorithms

-Browse for any file stored on your device, or on its SD card and calculate its hash.

-File hashing supports SHA-1, SHA-256, SHA-384, SHA-512, MD5 algorithms

-Fast file hashing

-No file size limit

-Quickly copy the hashing result to the clipboard

**Overall**

-Intuitive and simple to use interface

-More cool features related with cryptography are coming soon...

DISCLAIMER:

-In order to break encryption statistical analysis techniques are used such a Frequency Analysis, Index of Coincidence, Chi Squared etc. Therefore, the longest the text is, the better the algorithms will perform.

-RC4, Blowfish and AES algorithms currently use a randomized initialization vector
