parse

public static List<X509Certificate> parse(File pemFile)
                                   throws IOException,
                                          CertificateException

Parses a X.509 certificate chain from the specified PEM-encoded representation. PEM-encoded objects that are not X.509 certificates are ignored. Requires BouncyCastle.

Parameters:

pemFile - The PEM-encoded X.509 certificate chain file. Must not be null.

Returns:

The X.509 certificate chain, empty list if no certificates are found.

Throws:

IOException - On I/O exception.

CertificateException - On a certificate exception.

parse

public static List<X509Certificate> parse(String pemString)
                                   throws IOException,
                                          CertificateException

Parses a X.509 certificate chain from the specified PEM-encoded representation. PEM-encoded objects that are not X.509 certificates are ignored. Requires BouncyCastle.

Parameters:

pemString - The PEM-encoded X.509 certificate chain. Must not be null.

Returns:

The X.509 certificate chain, empty list if no certificates are found.

Throws:

IOException - On I/O exception.

CertificateException - On a certificate exception.

store

public static List<UUID> store(KeyStore trustStore,
                               List<X509Certificate> certChain)
                        throws KeyStoreException

Stores a X.509 certificate chain into the specified Java trust (key) store. The name (alias) for each certificate in the store is a generated UUID.

Parameters:

trustStore - The trust (key) store. Must be initialised and not null.

certChain - The X.509 certificate chain. Must not be null.

Returns:

The UUIDs for the stored entry.

Throws:

KeyStoreException - On a key store exception.
