The following are tools that, together, give you the power to do a compute a discrete logarithm with a birthday or baby-step-giant-step attack.

Setup (choose prime modulus p, primitive root g, and target h; set up R = Z/pZ)

 

Print some random powers of g

 

Print some random powers of g times h

 

Print some systematic powers of g

 

Print some systematic products of g and h
