Subject: [RFC PATCH 02/22] staging: crypto: skein: import code from Skein3Fish.git
Date: Tue, 11 Mar 2014 21:32:34 +0000 [thread overview]
Message-ID: <bdb4dad24d32d74a02736f83ab2f29992af6d041.1394570067.git.jason@lakedaemon.net> (raw)

In-Reply-To: <cover.1394570067.git.jason@lakedaemon.net>
This is a byte-for-byte copy of the skein implementation found at:
https://github.com/wernerd/Skein3Fish.git
Specifically, from the master branch at commit:
00e925444c2c Merge pull request #4 from csm/master
The next commit will do the minimum necessary to build this code as a
module.
I've generated the sha256 sums of the files by:
$ (cd drivers/staging/skein; find . -type f | sort | xargs sha256sum)

+ The unsigned integer types defined here are of the form uint_<nn>t where
+ <nn> is the length of the type; for example, the unsigned 32-bit type is
+ 'uint_32t'. These are NOT the same as the 'C99 integer types' that are
+ defined in the inttypes.h and stdint.h headers since attempts to use these
+ types have shown that support for them is still highly variable. However,
+ since the latter are of the form uint<nn>_t, a regular expression search
+ and replace (in VC++ search on 'uint_{:z}t' and replace with 'uint\1_t')
+ can be used to convert the types used here to the C99 standard types.

+ * @file skeinApi.h
+ * @brief A Skein API and its functions.
+ * @{
+ *
+ * This API and the functions that implement this API simplify the usage
+ * of Skein. The design and the way to use the functions follow the openSSL
+ * design but at the same time take care of some Skein specific behaviour
+ * and possibilities.
+ *
+ * The functions enable applications to create a normal Skein hashes and
+ * message authentication codes (MAC).
+ *
+ * Using these functions is simple and straight forward:
+ *
+ * @code
+ *
+ * #include <skeinApi.h>
+ *
+ * ...
+ * SkeinCtx_t ctx; // a Skein hash or MAC context
+ *
+ * // prepare context, here for a Skein with a state size of 512 bits.
+ * skeinCtxPrepare(&ctx, Skein512);
+ *
+ * // Initialize the context to set the requested hash length in bits
+ * // here request a output hash size of 31 bits (Skein supports variable
+ * // output sizes even very strange sizes)
+ * skeinInit(&ctx, 31);
+ *
+ * // Now update Skein with any number of message bits. A function that
+ * // takes a number of bytes is also available.
+ * skeinUpdateBits(&ctx, message, msgLength);
+ *
+ * // Now get the result of the Skein hash. The output buffer must be
+ * // large enough to hold the request number of output bits. The application
+ * // may now extract the bits.
+ * skeinFinal(&ctx, result);
+ * ...
+ * @endcode
+ *
+ * An application may use @c skeinReset to reset a Skein context and use
+ * it for creation of another hash with the same Skein state size and output
+ * bit length. In this case the API implementation restores some internal
+ * internal state data and saves a full Skein initialization round.
+ *
+ * To create a MAC the application just uses @c skeinMacInit instead of
+ * @c skeinInit. All other functions calls remain the same.
