createSigner

protected org.bouncycastle.crypto.Signer createSigner(org.bouncycastle.asn1.x509.AlgorithmIdentifier sigAlgId)
                                               throws OperatorCreationException

Description copied from class: BcContentVerifierProviderBuilder

Create the correct signer for the algorithm identifier sigAlgId.

Specified by:

createSigner in class BcContentVerifierProviderBuilder

Parameters:

sigAlgId - the algorithm details for the signature we want to verify.

Returns:

a Signer object.

Throws:

OperatorCreationException - if the Signer cannot be constructed.
