Thanks. btw, is the bivariate version of Coppersmith's method implemented anywhere? I mean the method based on this publication: Don Coppersmith, Finding a Small Root of a Bivariate Modular Equation; Factoring with High Bits Known, Advances in Cryptology - Eurocrypt'96, Springer-Verlag http://dsns.csie.nctu.edu.tw/research/crypto/HTML/E96.HTM Thanks, Max
