 //! \brief Keccak message digest base class

-//!   FIPS 202 conformance (XOF d=0x01) is available in SHA3 classes.
+//! \details The Crypto++ Keccak implementation uses F1600 with XOF d=0x01.
+//!   FIPS 202 conformance (XOF d=0x06) is available in SHA3 classes.
 //! \details Keccak is the base class for Keccak_224, Keccak_256, Keccak_384 and Keccak_512.
 //!   Library users should instantiate a derived class, and only use Keccak
 //!   as a base class reference or pointer.
 //! \details Keccak will likely change in the future to accomodate extensibility of the
 //!   round function and the XOF functions.
-//! \details Perform the following to specify a different digest size. The class will use F1600, 0x80,
-//!   and a new vaue for <tt>r()</tt> (which will be <tt>200-2*24 = 152</tt>).
