Class KyberPublicKey

java.lang.Object
com.ibm.crypto.hdwrCCA.provider.KyberPublicKey
All Implemented Interfaces:
Serializable, Key, PublicKey
@Deprecated(since="21.0.11.0", forRemoval=true) public final class KyberPublicKey extends Object implements PublicKey
Deprecated, for removal: This API element is subject to removal in a future version.
Replaced by ML-KEM implementation. This CRYSTALS-Kyber implementation is deprecated and will be removed in a future release, in alignment with NIST's latest recommendations for post-quantum cryptography modernization. Users should transition to the finalized ML-KEM standards.
A public hardware key for the CRYSTALS-Kyber algorithm. This key contains a token (which can be either a tokenized representation of a clear key, a key encrypted under the master key, or a label to a stored key in the PKDS), encoded bytes of the raw key material, and attributes (KeyHWAttributeValues, which include the key type and key usage).
