Method Detail

engineGeneratePublic

protected PublicKey engineGeneratePublic(KeySpec keySpec)
                                  throws InvalidKeySpecException

Generates a public key from the given key spec.

Specified by:

engineGeneratePublic in class KeyFactorySpi

Parameters:

keySpec - the key material; it may either be SLHDSAPublicKeySpec or X509EncodedKeySpec

Returns:

the generated public key

Throws:

InvalidKeySpecException - if the key spec is not supported or erroneous

engineGeneratePrivate

protected PrivateKey engineGeneratePrivate(KeySpec keySpec)
                                    throws InvalidKeySpecException

Generates a private key from the given key spec.

Specified by:

engineGeneratePrivate in class KeyFactorySpi

Parameters:

keySpec - the key material; it may either be SLHDSAPrivateKeySpec or PKCS8EncodedKeySpec

Returns:

the generated private key

Throws:

InvalidKeySpecException - if the key spec is not supported or erroneous

engineGetKeySpec

protected <T extends KeySpec> T engineGetKeySpec(Key key,
                                                 Class<T> keySpec)
                                          throws InvalidKeySpecException

Implementation of the engine method. Converts a key into its spec.

Specified by:

engineGetKeySpec in class KeyFactorySpi

Parameters:

key - the key to be converted (either SLHDSAPrivateKey or SLHDSAPublicKey)

keySpec - the key specification type. If the given key is of type SLHDSAPrivateKey the keySpec may be SLHDSAPrivateKeySpec or PKCS8EncodedKeySpec. Otherwise (key is of type SLHDSAPublicKey) the keySpec must be SLHDSAPublicKeySpec or X509EncodedKeySpec

Returns:

the corresponding key spec

Throws:

InvalidKeySpecException - if the key cannot be transformed into the provided keySpec.

engineTranslateKey

protected Key engineTranslateKey(Key key)
                          throws InvalidKeyException

Translates the given key object of some unknown or untrusted provider into a key object supported by this SLH-DSA key factory. This method can only translate keys of type SLHDSAPrivateKey or SLHDSAPublicKey.

Specified by:

engineTranslateKey in class KeyFactorySpi

Parameters:

key - the key to be translated

Returns:

the translated key

Throws:

InvalidKeyException - if the given key cannot be translated

translateKey

public static Key translateKey(Key key)
                        throws InvalidKeyException

Throws:

InvalidKeyException
