# EdECPoint

` public final class EdECPoint `   
` extends https://developer.android.com/reference/java/lang/Object ` ` `

|---|---|
| [java.lang.Object](https://developer.android.com/reference/java/lang/Object) ||

<br />

*** ** * ** ***

An elliptic curve point used to specify keys as defined by [RFC 8032: Edwards-Curve Digital Signature Algorithm (EdDSA)](https://tools.ietf.org/html/rfc8032). These points are distinct from the points represented by `ECPoint`, and they are intended for use with algorithms based on RFC 8032 such as the EdDSA `Signature` algorithm.

An EdEC point is specified by its y-coordinate value and a boolean that indicates whether the x-coordinate is odd. The y-coordinate is an element of the field of integers modulo some value p that is determined by the algorithm parameters. This field element is represented by a `BigInteger`, and implementations that consume objects of this class may reject integer values which are not in the range \[0, p).
