Create the signer using the given
||Human readable name of this signer.
Set a listener for being notified of important events that require user interaction.
||A LoadingFeedbackListener for receiving important events.
Can be used to provide a password to the signer, which might be used to unlock a private key (or similar).
||A password that should be used by the signer, or
null if no password is required.
KeyStore.PrivateKeyEntry used by this signer. Subclasses have to override this and have to make sure to call the provided
PrivateKeySigner.OnPrivateKeyLoadedCallback whenever private key is ready. The method might be called with a LoadingFeedbackListener which should be
used by the implementation to notify of important events (e.g. password required, key loading complete, etc.).
||An optional password that should be used to load the private key.
||A LoadingFeedbackListener to be notified of important loading events, or
PrivateKeySigner.OnPrivateKeyLoadedCallback that should be called once the private key has been loaded.
Signer whenever the implementation should prepare required signing parameters. This is an asynchronous operation, which is completed
by the implementation handing over the signing parameters using the given
Signer.OnSigningParametersReadyCallback. Signing parameters include:
SignatureProvider that implements the actual data signing logic (i.e. signing and hashing PDF data).
- The X509Certificate that is embedded to the PDF document while signing.
||An OnSigningParametersReadyCallback that should be called by the implementation to hand over all required signing parameters.
