'''Abstract''' In this paper we introduce Janus, a software framework – written in Java – which is built
 
to provide assistance in finding independent-biclique attacks for a user-chosen set of parameters,
 
e.g., number of rounds and dimension of the biclique. Given a certain cipher, Janus does not only
 
find an optimal bipartite graph (biclique), but also provides an all-round carefree package including
 
an optimal matching-with-precomputation step, rendering of the found biclique, the matching steps
 
and computation of the attack complexity.
 
We have used the Janus framework to verify existing results on the AES and ARIA. Additionally,
 
by using this framework, we could find the first full-round biclique attacks on all versions of the
 
AES-like cipher BKSQ.
