ECField

AI-generated Key Takeaways

• ECField represents an elliptic curve's finite field, which must be implemented by all specialized EC fields.

• Two known subclasses, ECFieldF2m and ECFieldFp, define characteristic 2 and prime finite fields, respectively.

• The primary method, getFieldSize(), returns the field size in bits, representing either the size of the prime 'p' or 'm' depending on the field type.

public interface ECField

Known Indirect Subclasses ECFieldF2m, ECFieldFp 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.
