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)

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.
