Detailed description

Result of the KEM (Key Encapsulation Mechanism) encapsulation operation.

Returned by Dinamo#kemEncaps(int, byte, String, byte[], int, int, byte[]). Contains the ciphertext that must be sent to the party that will decapsulate it, and when the operation is TacNDJavaLib#DN_KEM_OP_SHARED_SECRET, the generated shared secret.

Function documentation

getSharedSecret()

byte[] getSharedSecret

(

)

Returns the shared secret generated during the encapsulation operation.

Not null only when the operation specified in bOp is TacNDJavaLib#DN_KEM_OP_SHARED_SECRET. For the operations TacNDJavaLib#DN_KEM_OP_DIRECT_KEY and TacNDJavaLib#DN_KEM_OP_X9_63_SHA256 , the key is created directly in the HSM, and this field will return an empty array.

Returns

Shared secret or empty array when the key is created in the HSM.

getCiphertext()

byte[] getCiphertext

(

)

Returns the KEM (key-encapsulated material) ciphertext.

This value must be transmitted to the party that will perform the decapsulation using the private key corresponding to the public key used in the encapsulation.

Returns

KEM ciphertext.
