Method Detail

putCertificates

void putCertificates(java.security.cert.X509Certificate[] certificates)
                     throws X509TrustManagerException

Hands over a bunch of certificates to the trust management system in order to be stored for later use.

Parameters:

certificates - The bunch of certificates to be stored. May be null.

Throws:

X509TrustManagerException - if putting the certificates into the trust management system fails for any reason.

putCRL

void putCRL(java.security.cert.X509CRL cRL)
            throws X509TrustManagerException

Hands over a certificate revocation list to the trust management system in order to be stored there.

Parameters:

cRL - The certificate revocation list. May be null.

Throws:

X509TrustManagerException - if putting the CRL into the trust management system fails for any reason.

isTrusted

boolean isTrusted(java.security.cert.X509Certificate trustCandidate)
                  throws X509TrustManagerException

Decides if a specified certificate "is trusted" by the trust management system. This interface does not make any statements about the trust management system's trust model on wheter a certificate is considered "trusted" or not. For instance the trust management system could try to find a certification path from the particular certificate up to a CA certificate that is explicitely trusted by a profile; additionally it could check that all certificates in the path are valid and that their revocation information has been checked.

Parameters:

trustCandidate - The certificate to be tested. Must not be null.

Returns:

true if the certificate is trusted.

Throws:

X509TrustManagerException - if getting the trust decision fails for any reason.

getCertificate

java.security.cert.X509Certificate getCertificate(java.security.Principal issuer,
                                                java.math.BigInteger serialNumber)
                                                  throws X509TrustManagerException

Provides the certificate which is unambigously identified by the specified parameters.

Parameters:

issuer - The issuer of the certificate. Must not be null.

serialNumber - The serial number of the certificate. Must not be null.

Returns:

the certificate fitting for the specified parameters, or null, if the trust management system does not know this certificate.

Throws:

X509TrustManagerException - if getting the requested certificate fails for any reason.

getCertificate

java.security.cert.X509Certificate getCertificate(byte[] subjectKeyIdentifierValue)
                                                  throws X509TrustManagerException

Provides the certificate which is unambigously identified by the specified parameter.

Parameters:

subjectKeyIdentifierValue - The plain (i.e. non-DER-encoded) value of the X509.V3 certificate extension named SubjectKeyIdentifer (OID 2.5.29.14). Must not be null.

Returns:

the certificate fitting for the specified parameters, or null, if the trust management system does not know this certificate.

Throws:

X509TrustManagerException - if getting the requested certificate fails for any reason.

getCertificates

java.security.cert.X509Certificate[] getCertificates(java.security.Principal subject)
                                                     throws X509TrustManagerException

Provides all certificates whose subject equals the specified parameter.

Parameters:

subject - The subject of the certificate. Must not be null.

Returns:

an array of at all fitting certificates, or null if there are no fitting certificates.

Throws:

X509TrustManagerException - if getting the requested certificates fails for any reason.
