Method Summary

Modifier and Type	Method	Description
`static CRLValidity`	`buildCRLValidity(CRLBinary crlBinary, CertificateToken issuerToken)`	This method verifies and creates: the signature of the CRL, the key usage of its signing certificate and the coherence between the subject names of the CRL signing certificate and the issuer name of the certificate for which the verification of the revocation data is carried out.
`static X509CRLEntry`	`getRevocationInfo(CRLValidity crlValidity, BigInteger serialNumber)`	This method verifies the revocation status for a given serial number

```
public static CRLValidity buildCRLValidity(CRLBinary crlBinary,
                                           CertificateToken issuerToken)
                                    throws IOException
```
    This method verifies and creates: the signature of the CRL, the key usage of its signing certificate and the coherence between the subject names of the CRL signing certificate and the issuer name of the certificate for which the verification of the revocation data is carried out. A dedicated object based on CRLValidity is created and accordingly updated.
    
    Parameters:
    
    crlBinary - CRLBinary of the CRL to be created (cannot be null)
    
    issuerToken - CertificateToken used to sign the X509CRL (cannot be null)
    
    Returns:
    
    CRLValidity
    
    Throws:
    
    IOException - if an IO error occurred
  - getRevocationInfo
```
public static X509CRLEntry getRevocationInfo(CRLValidity crlValidity,
                                             BigInteger serialNumber)
```
    This method verifies the revocation status for a given serial number
    
    Parameters:
    
    crlValidity - the CRL Validity
    
    serialNumber - the certificate serial number to search
    
    Returns:
    
    the X509CRLEntry with the revocation date, the reason, or null if the serial number is not found
