XECPublicKeySpec

public class XECPublicKeySpec
extends Object implements KeySpec

java.lang.Object
↳	java.security.spec.XECPublicKeySpec

A class representing elliptic curve public keys as defined in RFC 7748, including the curve and other algorithm parameters. The public key is a particular point on the curve, which is represented using only its u-coordinate. A u-coordinate is an element of the field of integers modulo some value that is determined by the algorithm parameters. This field element is represented by a BigInteger which may hold any value. That is, the BigInteger is not restricted to the range of canonical field elements.

Summary

Public constructors
`XECPublicKeySpec(AlgorithmParameterSpec params, BigInteger u)` Construct a public key spec using the supplied parameters and u coordinate.

Public methods
`AlgorithmParameterSpec`	`getParams()` Get the algorithm parameters that define the curve and other settings.
`BigInteger`	`getU()` Get the u coordinate of the point.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
