Constructor Detail

CompositePublicKey

public CompositePublicKey(java.security.PublicKey... keys)

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

Parameters:

keys - The component public keys.

CompositePublicKey

public CompositePublicKey(ASN1ObjectIdentifier algorithmIdentifier,
                          java.security.PublicKey... keys)

Create a composite public key which corresponds to a composite signature algorithm in algorithmIdentifier. The component public 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 -

CompositePublicKey

public CompositePublicKey(SubjectPublicKeyInfo keyInfo)

Create a composite public key from a SubjectPublicKeyInfo.

Parameters:

keyInfo - SubjectPublicKeyInfo object containing a composite public key.

Method Detail

getPublicKeys

public java.util.List<java.security.PublicKey> getPublicKeys()

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

Returns:

an immutable list of public 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 composite public key encoded as a SubjectPublicKeyInfo. If the composite public key is legacy (MiscObjectIdentifiers.id_composite_key), it each component public key is wrapped in its own SubjectPublicKeyInfo. Other composite public keys are encoded according to https://www.ietf.org/archive/id/draft-ounsworth-pq-composite-sigs-13.html#name-compositesignaturepublickey where each component public key is a BIT STRING which contains the result of calling getEncoded() for each component public key.

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
