extractKeyParameters

protected abstract org.bouncycastle.crypto.params.AsymmetricKeyParameter extractKeyParameters(org.bouncycastle.asn1.x509.SubjectPublicKeyInfo publicKeyInfo)
                                                                                       throws java.io.IOException
Extract an AsymmetricKeyParameter from the passed in SubjectPublicKeyInfo structure.
Parameters:
publicKeyInfo - a publicKeyInfo structure describing the public key required.
Returns:
an AsymmetricKeyParameter object containing the appropriate public key.
Throws:
java.io.IOException - if the publicKeyInfo data cannot be parsed,

createSigner

protected abstract org.bouncycastle.crypto.Signer createSigner(org.bouncycastle.asn1.x509.AlgorithmIdentifier sigAlgId)
                                                        throws OperatorCreationException
Create the correct signer for the algorithm identifier sigAlgId.
Parameters:
sigAlgId - the algorithm details for the signature we want to verify.
Returns:
a Signer object.
Throws:
OperatorCreationException - if the Signer cannot be constructed.
