Method Details

detectFormat

public static String detectFormat(String format,
 String name)

Detects the keystore format from the given keystore file name.

loadKeyManagerFactory

public static KeyManagerFactory loadKeyManagerFactory(String keyStoreFormat,
 Resource keyStore,
 String keyStorePassword)
                                               throws KeyStoreException,
IOException,
NoSuchAlgorithmException,
CertificateException,
UnrecoverableKeyException

Creates a new KeyManagerFactory from the given KeyStore Resource.

Parameters:

keyStoreFormat - The format of the keystore.

keyStore - The resource containing the keystore.

keyStorePassword - The password for the keystore. May be empty or null.

Returns:

The newly created KeyManagerFactory.

Throws:

KeyStoreException - If the keystore format isn't supported.

IOException - If there is an I/O or format problem with the keystore data, if a password is required but not given, or if the given password was incorrect. If the error is due to a wrong password, the cause of the IOException should be an UnrecoverableKeyException

NoSuchAlgorithmException - If the algorithm used to check the integrity of the keystore cannot be found

CertificateException - If any of the certificates in the keystore could not be loaded

UnrecoverableKeyException - If the key cannot be recovered(e.g. the given password is wrong).

loadTrustManagerFactory

public static TrustManagerFactory loadTrustManagerFactory(String trustStoreFormat,
 Resource trustStore,
 String trustStorePassword)
                                                   throws KeyStoreException,
IOException,
NoSuchAlgorithmException,
CertificateException

Creates a new TrustManagerFactory from the given KeyStore Resource.

Parameters:

trustStoreFormat - The format of the truststore.

trustStore - The resource containing the truststore.

trustStorePassword - The password for the truststore. May be empty or null.

Returns:

The newly created KeyManagerFactory.

Throws:
