v2.21 Intel Intelligent Storage Acceleration Library Crypto Release Notes
================================================================================
================================================================================
RELEASE NOTE CONTENTS
================================================================================
1. KNOWN ISSUES
2. FIXED ISSUES
3. CHANGE LOG & FEATURES ADDED
================================================================================
1. KNOWN ISSUES
================================================================================
* Perf tests do not run in Windows environment.
* 32-bit lib is not supported in Windows.
================================================================================
2. FIXED ISSUES
================================================================================
v2.21
* Put correct vec instruction versions in aes_cbc_enc_{128,192,256}(). May help
performance on some systems.
v2.20
* Fix issue with new aes_gcm API, aes_gcm_pre_256 was incorrect.
* Multi-buffer hash max length extended. Previous max length for
{sha1,sha256,sha512,md5}_mb was 4095MB. While there is still a 4GB limit for
each submit, the total hashed length can now be larger then 4GB.
v2.18
* Fix for multi-buffer hash when total length is above 512MB.
v2.14
* Building in unit directories is no longer supported removing the issue of
leftover object files causing the top-level make build to fail.
v2.9
* Multi-buffer MD5 AVX2 tests fixed to work on FreeBSD 9.1 by explicitly aligning
structures.
v2.7
* Unit tests and examples are now supported in Windows environment
================================================================================
3. CHANGE LOG & FEATURES ADDED
================================================================================
v2.21
* Multi-buffer hash performance improvement for Intel(R) Atom(tm) processors.
New by-2 shani versions for multi-buffer sha1 & sha256.
* New base functions for multi-buffer hashes.
md5_mb, sha1_mb, sha256_mb, sha512_mb.
v2.20
* New functions
- Non-temporal versions of aes_gcm added.
* Multi-buffer hash improvement
- Increase max length of hash in {sha1,sha256,sha512,md5}_mb to > 4GB.
v2.19
* Multi-buffer hash (sha1_mb, sha256_mb)
- Choose fast single buffer routine to do flush operation if lanes aren't full.
- Add SHA-NI support for Goldmont and Cannonlake.
* AES-GCM interface updates.
- New interface separates the expanded keys and other context into two
structures. The old interface is maintained for backward compatibility.
- User no longer has to append the GCM_IV_END_MARK manually to then end of iv
as this is now done automatically. This update should also improve performance
of small packets.
* Rolling hash is released.
v2.18
* New multi-hash SHA256-based version.
v2.16
* Split lib from non-crypto functions.
v2.15
* Multi-buffer hash updates. New AVX512 versions for multi-buffer SHA1, SHA256,
SHA512, MD5 and SHA1+murmur3_x64_128 stitched.
* Removes restrictions on AAD length in AES-GCM. Previously AAD length was
limited to a multiple of 4 bytes. Now any AAD length is allowed.
* Nasm support. ISA-L ported to build with nasm or yasm assembler.
* Windows DLL support. Windows builds DLL by default.
* The older, deprecated multi-buffer API has been removed.
v2.14
* New multi-hash sha1 function and multi-hash sha1 + murmur3_x64_128 stitched.
Multi-hash is designed to give the performance of multi-buffer cryptographic
hashes with a synchronous single buffer interface.
* New AES-GCM and AES-CBC functions added.
* Autoconf and autotools build allows easier porting to additional systems.
Previous make system still available to embedded users with Makefile.unx.
* The AES key expand functions that were used for AES-XTS with pre-expanded keys
now expand the decrypt keys in a different order. The order that decrypt keys
are stored and used by XTS_AES_128_dec_expanded_key() is reversed from
previous versions to be compatable with CBC and GCM key expansion. The
aes_keyexp_*() and XTS_AES_128_dec_expanded_key() functions should work the
same when paired together.
* Includes update for building on Mac OS X/darwin systems. Add --target=darwin
to ./configure step.
v2.10
* Added multi-buffer MD5 in the new hash API. Includes multi-binary capability,
no restriction on update length and other benefits of the CTX API.
v2.9
* New multi-buffer hash API. The new API brings the following new features to
multi-buffer hashes. The older API is still included but may be deprecated in
future releases.
- Multibinary functionality. Call one function and the appropriate
architecture-specific version is fixed up at runtime.
- No restriction on update length. Submitting an update block no longer has
to have length a multiple of the fundamental block size.
* New expanded key tests added for AES-XTS 128 and 256
v2.7
* New AVX2 versions for mb_md5 and mb_sha512 hashing code have been added.
v2.6
* Update buffer functionality added to mb_md5, mb_sha256 and mb_sha512 hashing
code. Requires API changes to current interface to specify job type and total
length of hash.
* New AVX2 versions for mb_sha1 and mb_sha256 hashing code have been added.
v2.5
* New feature for multi-buffer SHA-1, update buffer. mb_sha1 non-finalize jobs
can now be submitted by setting flags in job structure. Requires API changes
to current interface to specify job type and total length of hash.
v2.4
* Added new multi-buffer SHA-512: mb_sha512. SSE, AVX versions.
v2.3
* Added improved AES XTS versions.
v2.2
* Added new AVX versions of multi-buffer hashes
* Changed type in the interface struct for multi-buffer hashes
the len field in the following structures :JOB_SHA1,JOB_MD5,
JOB_SHA256 is now a 32-bit int.
v2.0
* Added AES XTS units aes_xts_128, aes_xts_256
v1.3
* Added new multi-buffer units for SHA-256 and MD5: mb_sha256, mb_md5.
