Method Detail

• engineGeneratePrivate

  protected PrivateKey engineGeneratePrivate(KeySpec keySpec)
                                      throws InvalidKeySpecException

  Generates an EdDSA private key from the provided key specification. This method converts various key specification formats into EdDSA private keys, supporting both EdDSA-specific specifications and standard PKCS#8 encoding.

  Specified by:

  engineGeneratePrivate in class KeyFactorySpi

  Parameters:

  keySpec - the key specification to convert

  Returns:

  the generated EdDSA private key

  Throws:

  InvalidKeySpecException - if the key specification is unsupported or malformed

• engineGeneratePublic

  protected PublicKey engineGeneratePublic(KeySpec keySpec)
                                    throws InvalidKeySpecException

  Generates an EdDSA public key from the provided key specification. This method converts various key specification formats into EdDSA public keys, supporting both EdDSA-specific specifications and standard X.509 encoding.

  Specified by:

  engineGeneratePublic in class KeyFactorySpi

  Parameters:

  keySpec - the key specification to convert

  Returns:

  the generated EdDSA public key

  Throws:

  InvalidKeySpecException - if the key specification is unsupported or malformed

• engineGetKeySpec

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

  Returns a specification (key material) of the given key object. This method extracts the underlying key parameters from EdDSA keys and converts them into the requested specification format.

  Specified by:

  engineGetKeySpec in class KeyFactorySpi

  Type Parameters:

  T - the type of the returned key specification

  Parameters:

  key - the key

  keySpec - the requested specification class

  Returns:

  the corresponding key specification

  Throws:

  InvalidKeySpecException - if the requested specification type is unsupported or the key cannot be converted

• engineTranslateKey

  protected Key engineTranslateKey(Key key)
                            throws InvalidKeyException

  Translates a key object from one provider to another. This method would allow conversion between EdDSA keys from different security providers, but currently no other EdDSA providers are known or supported in the I2P environment.

  Specified by:

  engineTranslateKey in class KeyFactorySpi

  Parameters:

  key - the key

  Returns:

  the translated key

  Throws:

  InvalidKeyException - always, as no other EdDSA providers are supported
