Dear Benedikt, There is code to compute the Weil pairing using a gp script (written by me) which sage includes, but at present there is no wrapper for it to be used in Sage. Either that could be done, or someone could rewrite that gp script in Sage. John Cremona On 01/04/2008, Spit [EMAIL

Sounds like a good idea, and certainly vastly better than my gp code which was really only a toy. I CC'ed this so sge-devel. John On 01/04/2008, Martin Albrecht [EMAIL PROTECTED] wrote: Hi there, let me (ab)use this opportunity to point to a library for doing these things over finite

Hi there, let me (ab)use this opportunity to point to a library for doing these things over finite fields (for crypto) I came across by chance. http://crypto.stanford.edu/pbc/ PBC stands for Pairing-Based Cryptography and is a library for ... well ... pairings in cryptography (where
