Method Details

engineTranslateKey

protected Key engineTranslateKey(Key key)
                          throws InvalidKeyException

Specified by:

engineTranslateKey in class KeyFactorySpi

Throws:

InvalidKeyException

generatePrivate

public PrivateKey generatePrivate(PrivateKeyInfo keyInfo)
                           throws IOException

Creates a CompositePrivateKey from its PrivateKeyInfo encoded form. It is compliant with https://www.ietf.org/archive/id/draft-ounsworth-pq-composite-sigs-13.html where CompositeSignaturePrivateKey is a sequence of two OneAsymmetricKey which a newer name for PrivateKeyInfo.

Parameters:

keyInfo - PrivateKeyInfo containing a sequence of PrivateKeyInfos corresponding to each component.

Returns:

A CompositePrivateKey created from all components in the sequence.

Throws:

IOException

generatePublic

public PublicKey generatePublic(SubjectPublicKeyInfo keyInfo)
                         throws IOException

Creates a CompositePublicKey from its SubjectPublicKeyInfo encoded form. It is compliant with https://www.ietf.org/archive/id/draft-ounsworth-pq-composite-sigs-13.html where CompositeSignaturePublicKey is a sequence of two BIT STRINGs which contain the encoded component public keys. In BC implementation - CompositePublicKey is encoded into a BIT STRING in the form of SubjectPublicKeyInfo.

Parameters:

keyInfo - SubjectPublicKeyInfo containing a sequence of BIT STRINGs corresponding to each component.

Returns:

Throws:

IOException
