I can find no resources for doing elliptic curve cryptography. I have used the finite field package, but I find it cumbersome and it does not seem to have any builtin methods for ECC. How can I get started doing ECC in Mathematica?

  • $\begingroup$ I saw that, but it did not seem very practical. It's not really algorithms in Mathematica, its just a lecture on ECC written using Mathematica as a typesetter. $\endgroup$ – Tyler Durden Mar 11 '14 at 4:17
  • $\begingroup$ As you want something practical, consider not writing it yourself, and instead using JLink to use EC algorithms from Java 7's JCA/JCE API: docs.oracle.com/javase/7/docs/technotes/guides/security/… $\endgroup$ – Andreas Lauschke Mar 11 '14 at 5:46
  • $\begingroup$ @AndreasLauschke Yes, using a regular programming language, especially Python, is possible. Python has comprehensive crypto, plus there is a computational math system in Python called Sage that fully supports finite fields. I was just hoping that it would be already in Mathematica somehow. Of course, I could write all the modular arithematic needed from scratch, too, I suppose. $\endgroup$ – Tyler Durden Mar 11 '14 at 12:36
  • $\begingroup$ @Tyler: yes, I know Python is popular for crypto work. But you can't easily integrate it with M (at least to my knowledge), whereas with JLink it's right at your fingertips to leverage over from M to the JVM, and you mentioned "practical" in a comment. $\endgroup$ – Andreas Lauschke Mar 11 '14 at 17:21

A few updates, since Wolfram has added a lot of cryptography functionality in recent versions.

Here is a link to the guide page for Cryptography functions in the Wolfram Language:

https://reference.wolfram.com/language/guide/Cryptography.html

Here is a link to the lower level number theory functions related to cryptography:

https://reference.wolfram.com/language/guide/CryptographicNumberTheory.html

In response to the comment regarding Python, here is a new guide page related to calling Python (and other languages) directly from the Wolfram Language:
