Is there any place online where I can find the code for an algorithm which computes the shortest vector in a lattice?
The library only includes the algorithm for LLL.

Have a look at this paper by Fincke and Pohst:
http://www.ams.org/journals/mcom/1985-44-170/S0025-5718-1985-0777278-8/S0025-5718-1985-0777278-8.pdf
In particular, algorithm 2.8 on page 465 should help you.
You should be able to find the code for Keith Mathews' implementation somewhere near here:
