Class Inheritance
All Implemented Interfaces
java.security.spec.AlgorithmParameterSpec
Imports
java.security.spec.AlgorithmParameterSpec
This immutable class is used when randomly generating a key pair and the consumer only specifies the length of the key and therefore a curve for that key size must be picked from the list of supported curves using this spec.
