Subject: [RFC PATCH 0/4] crypto: Add support for shake128/256 XOFs

This series adds support for shake128/256 extended output functions (XOFs)
along with test cases to verify the produced digest and XOF output. A new
squeeze method is added to the shash_alg structure to get an arbitrary
number of bytes from these XOFs.

Regards,
   Stefan

Stefan Berger (4):
  crypto: Add squeeze function to shash_alg for support of XOFs
  crypto: Add shake128/256 to generic sha3 module
  crypto: Add tests cases for shake128 & shake256 to testmgr
  crypto: Extend testmgr with tests for shake128/256 XOFs
