setRegisterBouncyCastle

public static void setRegisterBouncyCastle(boolean registerBouncyCastle)

getSecurityProvider

public static String getSecurityProvider()

isBouncyCastleRegistered

loadKeyPairIdentity

public static KeyPair loadKeyPairIdentity(String resourceKey,
                                          InputStream inputStream,
                                          FilePasswordProvider provider)
                                   throws IOException,
                                          GeneralSecurityException

Parameters:

resourceKey - An identifier of the key being loaded - used as argument to the FilePasswordProvider.getPassword(String) invocation

inputStream - The InputStream for the private key

provider - A FilePasswordProvider - may be null if the loaded key is guaranteed not to be encrypted

Returns:

The loaded KeyPair

Throws:

IOException - If failed to read/parse the input stream

GeneralSecurityException - If failed to generate the keys - specifically, NoSuchProviderException is thrown also if isBouncyCastleRegistered() is false
