 # Curves
+ECTester contains a collection of elliptic curve/point parameters, these parameters either come from standards or

+### anomalous
 These prime field curves have the same order as the field order, and are susceptible to attacks reducing ECDLP over a multiplicative group of the curve, to DLP over an additive group of the underlying field, which is easy (linear time).
 
 Some of these are from Atsuko Miyaji's [paper](https://dspace.jaist.ac.jp/dspace/bitstream/10119/4464/1/73-61.pdf), others were generated using [ecgen](htps://github.com/J08nY/ecgen).
 
-## invalid
+### invalid
 This category contains pre-generated invalid curves for a large subset of NIST, SECG and Brainpool curves. Invalid curves for a given curve, are short Weierstrass curves with all parameters equal to the given curve except the `b` parameter. These curves can be used to [attack some implementations](https://www.nds.rub.de/media/nds/veroeffentlichungen/2015/09/14/main-full.pdf).

+### wrong
+Contains parameters that are not elliptic curves(over Fp and F2m), such as `p` parameter that is not prime or an irreducible polynomial that is not irreducible.

-## wrong
-Contains parameters that are not elliptic curves(over Fp and F2m), such as `p` parameter that is not prime, irreducible polynomial that is not irreducible and similar.
+### twist
+Contains pre-generated points on twists of known named curves from NIST, SECG.
+These points can be used to attack some implementations.
