Rabbit (cipher)

Rabbit is a stream cipher that uses a key with a length of 128 bits and a 64-bit initialization vector.

The algorithm was developed by Martin Boesgaard, Mette Veste Rager, Thomas Christensen and Erik Zenner at the company Cryptico.

In May 2005, Rabbit has been submitted as a candidate for the eSTREAM project and the Phase 2 (algorithms, which are further examined) has been reached.

For non-commercial use of the Rabbit algorithm is freely available.
