isSigningCapable

public boolean isSigningCapable()

Description copied from interface: StateAwareSignature

Return true if this Signature object can be used for signing. False otherwise.

Specified by:

isSigningCapable in interface StateAwareSignature

Returns:

true if we are capable of making signatures.

getUpdatedPrivateKey

public PrivateKey getUpdatedPrivateKey()

Description copied from interface: StateAwareSignature

Return the current version of the private key with the updated state.

Note: calling this method will effectively disable the Signature object from being used for further signature generation without another call to initSign().

Specified by:

getUpdatedPrivateKey in interface StateAwareSignature

Returns:

an updated private key object, which can be used for later signature generation.
