Method Detail

getClientIdentities

public static List<String> getClientIdentities(X509Certificate x509Certificate)

Returns the identities of the remote client as defined in the specified certificate. The identities are mapped by the classes in the "provider.clientCertIdentityMap.classList" property. By default, the subjectDN of the certificate is used.

Parameters:

x509Certificate - the certificate the holds the identities of the remote server.

Returns:

the identities of the remote client as defined in the specified certificate.

getServerIdentities

public static List<String> getServerIdentities(X509Certificate x509Certificate)

Returns the identities of the remote server as defined in the specified certificate. The identities are mapped by the classes in the "provider.serverCertIdentityMap.classList" property. By default, the identities are defined in the subjectDN of the certificate and it can also be defined in the subjectAltName extensions of type "xmpp". When the extension is being used then the identities defined in the extension are going to be returned. Otherwise, the value stored in the subjectDN is returned.

Parameters:

x509Certificate - the certificate the holds the identities of the remote server.

Returns:

the identities of the remote server as defined in the specified certificate.

isSelfSignedCertificate

public static boolean isSelfSignedCertificate(X509Certificate certificate)

Returns true if the specified certificate is a self-signed certificate.

Returns:

true if the specified certificate is a self-signed certificate.

isSigningRequestPending

public static boolean isSigningRequestPending(X509Certificate certificate)

Returns true if the specified certificate is ready to be signed by a Certificate Authority. Self-signed certificates need to get their issuer information entered to be able to generate a Certificate Signing Request (CSR).

Returns:

true if the specified certificate is ready to be signed by a Certificate Authority.

createSigningRequest

public static String createSigningRequest(X509Certificate cert,
                                          PrivateKey privKey)
                                   throws org.bouncycastle.operator.OperatorCreationException,
                                          IOException

Creates and returns the content of a new singing request for the specified certificate. Signing requests are required by Certificate Authorities as part of their signing process. The signing request contains information about the certificate issuer, subject DN, subject alternative names and public key. Private keys are not included. After the Certificate Authority verified and signed the certificate a new certificate is going to be returned.

Parameters:

cert - the certificate to create a signing request.

privKey - the private key of the certificate.

Returns:

the content of a new singing request for the specified certificate.

Throws:

org.bouncycastle.operator.OperatorCreationException

IOException

toPemRepresentation

public static String toPemRepresentation(Object object)
                                  throws IOException

Generates a PEM representation of the input argument.

Parameters:

object - the input argument (cannot be null).

Returns:

PEM representation of the input argument.

Throws:

IOException - When a PEM representation of the input could not be created.

parsePrivateKey

public static PrivateKey parsePrivateKey(String pemRepresentation,
                                         String passPhrase)
                                  throws IOException

Throws:

IOException

parsePrivateKey

public static PrivateKey parsePrivateKey(InputStream pemRepresentation,
                                         String passPhrase)
                                  throws IOException

Parses a PrivateKey instance from a PEM representation. When the provided key is encrypted, the provided pass phrase is applied.

Parameters:

pemRepresentation - a PEM representation of a private key (cannot be null or empty)

passPhrase - optional pass phrase (must be present if the private key is encrypted).

Returns:

a PrivateKey instance (never null)

Throws:

IOException

parseCertificates

public static Collection<X509Certificate> parseCertificates(String pemRepresentation)
                                                     throws IOException,
                                                            CertificateException

Throws:

IOException

CertificateException

parseCertificates

public static Collection<X509Certificate> parseCertificates(InputStream pemRepresentation)
                                                     throws IOException,
                                                            CertificateException

Parses a certificate chain from a PEM representation.

Parameters:

pemRepresentation - a PEM representation of a certificate or certificate chain (cannot be null or empty)

Returns:

A collection of certificates (possibly empty, but never null).

Throws:

IOException

CertificateException

addListener

public static void addListener(CertificateEventListener listener)

Registers a listener to receive events.

Parameters:

listener - the listener.

removeListener

public static void removeListener(CertificateEventListener listener)

Unregisters a listener to receive events.

Parameters:

listener - the listener.

fireCertificateStoreChanged

public static void fireCertificateStoreChanged(CertificateStore store)

Notify listeners that a certificate store has been changed.

order

@Deprecated
public static List<X509Certificate> order(Collection<X509Certificate> certificates)
                                               throws CertificateException

Deprecated. Moved to CertificateUtils

Orders certificates, starting from the entity to be validated and progressing back toward the CA root. This implementation matches "issuers" to "subjects" of certificates in such a way that "issuer" value of a certificate matches the "subject" value of the next certificate. When certificates are provided that do not belong to the same chain, a CertificateException is thrown.

Parameters:

certificates - an unordered collection of certificates (cannot be null).

Returns:

An ordered list of certificates (possibly empty, but never null).

Throws:

CertificateException
