Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`void`	`testKeyGenIsDeterministic()`
`void`	`testKeyGenRequiresMin32ByteIkm()`
`void`	`testKeyGenSeparation()`
`void`	`testKeyValidateRejectsForeignCurveSharingField()`
`void`	`testKeyValidateRejectsIdentity()`
`void`	`testKeyValidateRejectsNull()`
`void`	`testKeyValidateRejectsOffCurve()` ECCurve.createPoint does not check the curve equation, and the G1 subgroup check never uses b, so it accepts the image (u^2 x, u^3 y) of a G1 point on the isomorphic curve y^2 = x^3 + 4u^6. keyValidate must reject it by the curve equation.
`void`	`testKeyValidateRejectsOffSubgroup()`
`void`	`testKeyValidateRejectsSmallOrder()` (0, 2) is on the curve and has order 3, so it is outside G1.
