public void init(PGPContentVerifierBuilderProvider verifierBuilderProvider, PGPPublicKey pubKey) throws PGPException

Initialise the signature object for verification.

Parameters
verifierBuilderProvider:PGPContentVerifierBuilderProvider

provider for a content verifier builder for the signature type of interest.

pubKey:PGPPublicKey

the public key to use for verification

Exceptions
PGPException:
if there's an issue with creating the verifier.
isContainingback to summary
public boolean isContaining()

Return true, if the signature is contains any signatures that follow. An bracketing OPS is followed by additional OPS packets and is calculated over all the data between itself and its corresponding signature (it is an attestation for contained signatures).

Returns:boolean

true if containing, false otherwise
