+title: A Gentle Introduction to Elliptic-Curve Cryptography
+date: 2014-12-31 16:33:00 CEST
+category: links
+link: http://media.ccc.de/browse/congress/2014/31c3_-_6369_-_en_-_saal_1_-_201412272145_-_ecchacks_-_djb_-_tanja_lange.html#video

+A talk by djb and Tanja Lange.
+
+> This talk will explain how to work with elliptic curves constructively to obtain secure and efficient implementations, and will highlight pitfalls that must be avoided when implementing elliptic-curve crypto (ECC). The talk will also explain what all the buzz in curve choices for TLS is about. This talk does not require any prior exposure to ECC.
+
+The slides can be found [here](https://events.ccc.de/congress/2014/Fahrplan/system/attachments/2502/original/20141227-twopage.pdf) (CAcert) and the example source code is available [here](http://ecchacks.cr.yp.to).
