; License information:
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; This implementation notably advances the performance of SHA-1 algorithm compared to existing
; implementations. We are encouraging all projects utilizing SHA-1 to integrate this new fast
; implementation and are ready to help if issues or concerns arise (you are welcome to leave
; a comment or write an email to the authors). It is provided 'as is' and free for either
; commercial or non-commercial use.
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
;
; This code implements two interfaces of SHA-1 update function: 1) working on a single
; 64-byte block and 2) working on a buffer of multiple 64-bit blocks. Multiple blocks
; version of code is software pipelined and faster overall, it is a default. Assemble
; with -DINTEL_SHA1_SINGLEBLOCK to select single 64-byte block function interface.
;
; C++ prototypes of implemented functions are below:
;
; #ifndef INTEL_SHA1_SINGLEBLOCK
; // Updates 20-byte SHA-1 record in 'hash' for 'num_blocks' consequtive 64-byte blocks
; extern "C" void sha1_update_intel(int *hash, const char* input, size_t num_blocks );
; #else
; // Updates 20-byte SHA-1 record in 'hash' for one 64-byte block pointed by 'input'
; extern "C" void sha1_update_intel(int *hash, const char* input);
; #endif
;
; Function name 'sha1_update_intel' can be changed in the source or via macro:
; -DINTEL_SHA1_UPDATE_FUNCNAME=my_sha1_update_func_name
;
; It implements both UNIX(default) and Windows ABIs, use -DWIN_ABI on Windows
;
; Code checks CPU for SSSE3 support via CPUID feature flag (CPUID.1.ECX.SSSE3[bit 9]==1),
; and performs dispatch. Since in most cases the functionality on non-SSSE3 supporting CPUs
; is also required, the default (e.g. one being replaced) function can be provided for
; dispatch on such CPUs, the name of old function can be changed in the source or via macro:
; -DINTEL_SHA1_UPDATE_DEFAULT_DISPATCH=default_sha1_update_function_name

form, that is based on (or derived from) the Work and for which the

of this License, Derivative Works shall not include works that remain
separable from, or merely link (or bind by name) to the interfaces of,
the Work and Derivative Works thereof.
"Contribution" shall mean any work of authorship, including
the original version of the Work and any modifications or additions
to that Work or Derivative Works thereof, that is intentionally
submitted to Licensor for inclusion in the Work by the copyright owner
or by an individual or Legal Entity authorized to submit on behalf of
the copyright owner. For the purposes of this definition, "submitted"
means any form of electronic, verbal, or written communication sent
to the Licensor or its representatives, including but not limited to

"Contributor" shall mean Licensor and any individual or Legal Entity
on behalf of whom a Contribution has been received by Licensor and

3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works

pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.

whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.
