java.security: public interface: AlgorithmConstraints

java.security
public interface: AlgorithmConstraints [javadoc | source] This interface specifies constraints for cryptographic algorithms, keys (key sizes), and other algorithm parameters.

{@code AlgorithmConstraints} objects are immutable. An implementation of this interface should not provide methods that can change the state of an instance once it has been created.

Note that {@code AlgorithmConstraints} can be used to represent the restrictions described by the security properties {@code jdk.certpath.disabledAlgorithms} and {@code jdk.tls.disabledAlgorithms}, or could be used by a concrete {@code PKIXCertPathChecker} to check whether a specified certificate in the certification path contains the required algorithm constraints.

Method from java.security.AlgorithmConstraints Detail:
public boolean permits(Set<CryptoPrimitive> primitives, Key key) Determines whether a key is granted permission for the specified cryptographic primitives. This method is usually used to check key size and key usage.
public boolean permits(Set<CryptoPrimitive> primitives, String algorithm, AlgorithmParameters parameters) Determines whether an algorithm is granted permission for the specified cryptographic primitives.
public boolean permits(Set<CryptoPrimitive> primitives, String algorithm, Key key, AlgorithmParameters parameters) Determines whether an algorithm and the corresponding key are granted permission for the specified cryptographic primitives.
