- Method Detail
  - hasAssociatedCertificate
```
boolean hasAssociatedCertificate()
```
    Return whether or not this verifier has a certificate associated with it.
    
    Returns:
    
    true if there is an associated certificate, false otherwise.
  - getAssociatedCertificate
```
X509CertificateHolder getAssociatedCertificate()
```
    Return the associated certificate if there is one.
    
    Returns:
    
    a holder containing the associated certificate if there is one, null if there is not.
  - get
```
ContentVerifier get(org.bouncycastle.asn1.x509.AlgorithmIdentifier verifierAlgorithmIdentifier)
             throws OperatorCreationException
```
    Return a ContentVerifier that matches the passed in algorithm identifier,
    
    Parameters:
    
    verifierAlgorithmIdentifier - the algorithm and parameters required.
    
    Returns:
    
    a matching ContentVerifier
    
    Throws:
    
    OperatorCreationException - if the required ContentVerifier cannot be created.
