protected PrivateKey engineGeneratePrivate(KeySpec keySpec) throws InvalidKeySpecException

Overrides org.bouncycastle.jcajce.provider.asymmetric.util.BaseKeyFactorySpi.engineGeneratePrivate.

Doc from java.security.KeyFactorySpi.engineGeneratePrivate.

Generates a private key object from the provided key specification (key material).

Parameters
keySpec:KeySpec

the specification (key material) of the private key.

Returns:PrivateKey

the private key.

Exceptions
InvalidKeySpecException:
if the given key specification is inappropriate for this key factory to produce a private key.

protected PublicKey engineGeneratePublic(KeySpec keySpec) throws InvalidKeySpecException

Overrides org.bouncycastle.jcajce.provider.asymmetric.util.BaseKeyFactorySpi.engineGeneratePublic.

Doc from java.security.KeyFactorySpi.engineGeneratePublic.

Generates a public key object from the provided key specification (key material).

Parameters
keySpec:KeySpec

the specification (key material) of the public key.

Returns:PublicKey

the public key.

Exceptions
InvalidKeySpecException:
if the given key specification is inappropriate for this key factory to produce a public key.
engineGetKeySpecback to summary
protected KeySpec engineGetKeySpec(Key key, Class<T> spec) throws InvalidKeySpecException

Overrides org.bouncycastle.jcajce.provider.asymmetric.util.BaseKeyFactorySpi.engineGetKeySpec.

Doc from java.security.KeyFactorySpi.engineGetKeySpec.

Returns a specification (key material) of the given key object. keySpec identifies the specification class in which the key material should be returned. It could, for example, be DSAPublicKeySpec.class, to indicate that the key material should be returned in an instance of the DSAPublicKeySpec class.

Parameters
key:Key

the key.

spec:Class<T>

the specification class in which the key material should be returned.

Returns:KeySpec

the underlying key specification (key material) in an instance of the requested specification class.

Exceptions
InvalidKeySpecException:
if the requested key specification is inappropriate for the given key, or the given key cannot be dealt with (e.g., the given key has an unrecognized format).
engineTranslateKeyback to summary
protected Key engineTranslateKey(Key key) throws InvalidKeyException

Implements abstract java.security.KeyFactorySpi.engineTranslateKey.

Doc from java.security.KeyFactorySpi.engineTranslateKey.

Translates a key object, whose provider may be unknown or potentially untrusted, into a corresponding key object of this key factory.

Parameters
key:Key

the key whose provider is unknown or untrusted.

Returns:Key

the translated key.

Exceptions
InvalidKeyException:
if the given key cannot be processed by this key factory.
