Constructor Detail

RevokedCertifcateStore

private RevokedCertifcateStore()

Create the instance of RevokedCertificateStore. To fill the revocation table the default crls are loaded from a path

Parameters:

a_crl - the crl to add the revocations from

getInstance

public static RevokedCertifcateStore getInstance()

Returns the instance of RevokedCertificateStore (Singleton). If there is no instance, there is a new one created.

Returns:

the RevokedCertificateStore instance.

keyValue

private static java.lang.String keyValue(JAPCertificate a_cert)

Creates a concatenation of the certificate's issuer and its (pseudo-)serial.

Parameters:

a_cert - the certificate to create the value from

Returns:

the Key value to search the Hashtable

isCertificateRevoked

public boolean isCertificateRevoked(JAPCertificate a_cert)

Checks if the given cert is revoked.

Parameters:

a_cert - the cert to check

Returns:

true if the store contains a revocation for the cert, false otherwise

getRevocationDate

public java.util.Date getRevocationDate(JAPCertificate a_cert)
