**Quadratic two integer variable equation solver** (updated Dec 15th, 2003)

Solves quadratic Diophantine equations (integer equations of the form a x^2 + b xy + c y^2 + dx + ey + f = 0). Now it includes the source code.

**Factorization using the Elliptic Curve Method (ECM)** (updated August 22nd, 2010)

Applet that can be used to find 20- or 30-digit factors of numbers or numerical expressions up to 1000 digits long. It also computes the number and sum of divisors, Euler's totient and Moebius, and its decomposition as a sum of up to 4 perfect squares.

**Discrete logarithm calculator** (updated March 30th, 2002)
