Ĉifri APPLICATION description

Tiny text encryption / decryption utility
Tiny toyish text encryption / decryption utility with seamless integration into Android OS.
Requires offline key exchange between participants before can be used.

Encryption is performed using Bouncy Castle library. Three separate ciphers AES, Twofish and Serpent are chained on a block level into a single block-cipher. Messages are encrypted in CBC mode with PKCS7 padding.
Message integrity is protected by MAC code that is integrated into a message (using 'encrypt then MAC' construct)

Implementation is fully open-source, reviewers are welcome: https://github.com/quarck/cxifri
