The TElBuiltInCryptoProvider class in SecureBlackbox V10 ( have a public constructor but in the latest version ( it becomes 'inaccessible due to its protection level'. The constructor is now protected internal.

Is there any information on the site about this change?
How should this be used now?

(It is the same for TElWin32CryptoProvider).

Example usage:

if(TElHashFunction.IsAlgorithmSupported(SBConstants.Unit.SB_ALGORITHM_DGST_MD5, new TElBuiltInCryptoProvider()))

TElHashFunction hashFunction = new TElHashFunction(SBConstants.Unit.SB_ALGORITHM_DGST_MD5, new TElWin32CryptoProvider());

SecureBlackbox (NET_45_Win32)
OS: Win 8 Pro x64
VisualStudio 2013

Thank you for contacting us.

You should aquire instances of cryptoproviders using SBCryptoProvBuiltIn.Unit.BuiltInCryptoProvider() and SBCryptoProvWin32.Unit.Win32CryptoProvider() methods.

BTW, why do you need to create cryptoprovider objects? TElBuiltInCryptoProvider is used by default and may be ommited in TElHashFunction constructor. Also if an algorithm is supported by TElBuiltInCryptoProvider it doesn't mean that its supported by TElWin32CryptoProvider.
