                     throws TRHashProviderRegisterException

Use this method to register your custom hash provider. The method will throw exception if there is already a provider registered with the encryption.

Parameters:

encryption - - a unique name for encryption e.g. Scrypt

provider - - an implementation of TRHashProvider

Throws:

TRHashProviderRegisterException - - throws exception if a provider is already registered for an encryption.
