ECField
interface ECField
Known Direct Subclasses
| ECFieldF2m |
This immutable class defines an elliptic curve (EC) characteristic 2 finite field.
|
| ECFieldFp |
This immutable class defines an elliptic curve (EC) prime finite field.
|
|
This interface represents an elliptic curve (EC) finite field. All specialized EC fields must implements this interface.

getFieldSize
abstract fun getFieldSize(): Int
Returns the field size in bits. Note: For prime finite field ECFieldFp, size of prime p in bits is returned. For characteristic 2 finite field ECFieldF2m, m is returned.
