I want to extensively test my implementation of point addition and doubling. I have only one test vector with me. I need more values to test.

In the web, I could find test vectors only for key pair generation and signature verification. So if anybody can refer me a link containing test vectors, it will be of great help!


  • $\begingroup$ You could check your implementation against existing, well-established tools like sage. $\endgroup$

  • $\begingroup$ @yyyyyyy Can you share with me the exact page where test vectors are given in that site?. I couldnt find anything $\endgroup$

    $\begingroup$ yyyyyyy probably means that you should generate your own test vectors by executing those operations in sage. $\endgroup$

  • $\begingroup$ @Arjtom B Using sage to generate my own test vectors requires downloading the tool. Right now I'm not authorized to download tools as such $\endgroup$

1 Answer 1


You can check Elliptic Curve Calculator. It has point addition and scalar multiplication. For doubling, adding the same points(P+P) should do the work.
