Constructor Detail

CompositePrivateKey

public CompositePrivateKey(java.security.PrivateKey... keys)

Create a composite private key from an array of PublicKeys. This constructor is currently used only for legacy composites implementation.

Parameters:

keys - The component private keys.

CompositePrivateKey

public CompositePrivateKey(ASN1ObjectIdentifier algorithmIdentifier,
                           java.security.PrivateKey... keys)

Create a composite private key which corresponds to a composite signature algorithm in algorithmIdentifier. The component private keys are not checked if they satisfy the composite definition at this point, however, they will fail when they are fed into component algorithms which are defined by the algorithmIdentifier.

Parameters:

algorithmIdentifier -

keys -

CompositePrivateKey

public CompositePrivateKey(PrivateKeyInfo keyInfo)

Create a composite private key from a PrivateKeyInfo.

Parameters:

keyInfo - PrivateKeyInfo object containing a composite private key.

Method Detail

getPrivateKeys

public java.util.List<java.security.PrivateKey> getPrivateKeys()

Return a list of the component private keys making up this composite.

Returns:

an immutable list of private keys.

getAlgorithm

public java.lang.String getAlgorithm()

Specified by:

getAlgorithm in interface java.security.Key

getAlgorithmIdentifier

public ASN1ObjectIdentifier getAlgorithmIdentifier()

getFormat

public java.lang.String getFormat()

Specified by:

getFormat in interface java.security.Key

getEncoded

public byte[] getEncoded()

Returns the encoding of the composite private key. It is compliant with https://www.ietf.org/archive/id/draft-ounsworth-pq-composite-sigs-13.html#name-compositesignatureprivateke as each component is encoded as a PrivateKeyInfo (older name for OneAsymmetricKey).

Specified by:

getEncoded in interface java.security.Key

Returns:

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object
