AlgorithmConstraints
interface AlgorithmConstraints
This interface specifies constraints for cryptographic algorithms, keys (key sizes), and other algorithm parameters.
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 AlgorithmConstraints
can be used to represent the restrictions described by the security properties jdk.certpath.disabledAlgorithms
and jdk.tls.disabledAlgorithms
, or could be used by a concrete PKIXCertPathChecker
to check whether a specified certificate in the certification path contains the required algorithm constraints.

Public methods
permits
abstract fun permits(
primitives: MutableSet<CryptoPrimitive!>!,
algorithm: String!,
parameters: AlgorithmParameters!
): Boolean
Determines whether an algorithm is granted permission for the specified cryptographic primitives.
Return |
Boolean |
true if the algorithm is permitted and can be used for all of the specified cryptographic primitives |
Exceptions |
java.lang.IllegalArgumentException |
if primitives or algorithm is null or empty |
permits
abstract fun permits(
primitives: MutableSet<CryptoPrimitive!>!,
key: Key!
): Boolean
Determines whether a key is granted permission for the specified cryptographic primitives.
This method is usually used to check key size and key usage.
Return |
Boolean |
true if the key can be used for all of the specified cryptographic primitives |
Exceptions |
java.lang.IllegalArgumentException |
if primitives is null or empty, or the key is null |

Return |
Boolean |
true if the key and the algorithm can be used for all of the specified cryptographic primitives |
