What is SageMath?
SageMath (previously Sage or SAGE, "System for Algebra and Geometry Experimentation"[3]) is a computer algebra system (CAS) with features covering many aspects of mathematics, including algebra, combinatorics, graph theory, numerical analysis, number theory, calculus and statistics.
The first version of SageMath was released on 24 February 2005 as free and open-source software under the terms of the GNU General Public License version 2, with the initial goals of creating an "open source alternative to Magma, Maple, Mathematica, and MATLAB".[4] The originator and leader of the SageMath project, William Stein, was a mathematician at the University of Washington.
SageMath uses a syntax resembling Python's,[5] supporting procedural, functional and object-oriented constructs.
In simple terms, it is an open-source alternative to Mathematica and MATLAB. Due to its powerful cryptographic capabilities, it is often used by CTF Crypto enthusiasts for creating (and solving) challenges.
