+Intel(R) Intelligent Storage Acceleration Library Crypto Version
+================================================================
+
+ISA-L_crypto is a collection of optimized low-level functions targeting storage
+applications.  ISA-L_crypto includes:
+
+* Multi-buffer hashes - run multiple hash jobs together on one core for much
+  better throughput than single-buffer versions.
+  - SHA1, SHA256, SHA512, MD5, SM3
+
+* Multi-hash - Get the performance of multi-buffer hashing with a single-buffer
+  interface. Specification ref : [Multi-Hash white paper](https://www.intel.com/content/dam/www/public/us/en/documents/white-papers/multi-hash-paper.pdf)
+
+* Multi-hash + murmur - run both together.
+
+* AES - block ciphers
+  - XTS, GCM, CBC
+
+* Rolling hash - Hash input in a window which moves through the input
+
+Also see:
+* [ISA-L_crypto for updates](https://github.com/intel/isa-l_crypto).
+* For non-crypto ISA-L see [isa-l on github](https://github.com/intel/isa-l).
+* The [github wiki](https://github.com/intel/isa-l/wiki) covering isa-l and
+  isa-l crypto.

+
+Building ISA-L
+--------------
+
+### Prerequisites
+
+* Assembler: nasm v2.11.01 or later (nasm v2.13 or better suggested for building in AVX512 support)
+  or yasm version 1.2.0 or later.
+* Compiler: gcc, clang, icc or VC compiler.
+* Make: GNU 'make' or 'nmake' (Windows).
+* Optional: Building with autotools requires autoconf/automake packages.
+
+### Autotools
+To build and install the library with autotools it is usually sufficient to run:
+
+    ./autogen.sh
+    ./configure
+    make
+    sudo make install
+
+### Makefile
+To use a standard makefile run:
+
+    make -f Makefile.unx
+
+### Windows
+On Windows use nmake to build dll and static lib:
+
+    nmake -f Makefile.nmake
+
+### Other make targets
+Other targets include:
+* `make check` : create and run tests
+* `make tests` : create additional unit tests
+* `make perfs` : create included performance tests
+* `make ex`    : build examples
+* `make doc`   : build API manual
