java.security.interfaces

This package provides the interfaces needed to generate: (1) Keys for the RSA asymmetric encryption algorithm using the PKCS#1 standard; (2) Keys for the Digital Signature Algorithm (DSA) specified by FIPS-186; (3) Keys for a generic Elliptic Curve asymmetric encryption algorithm.
