disable 5x interleave on buffers shorter than 512 bytes: 3% speedup on Graviton2 d6e4287c9726691e800bff221be71edd894a3c6a introduced 5x interleaving as an optimization for ThunderX2, and that leads to some performance degradation on when encoding short buffers. We found this performance degradation by measuring the performance of nginx on Ubuntu 20.04 that comes with OpenSSL 1.1.1f and Ubuntu 22.04 with OpenSSL 3.0.1. This patch limits the 5x interleave to buffers larger than 512 bytes. On Graviton2 we see the following performance with this patch: $ openssl speed -evp aes-128-gcm -bytes 128 AES-128-GCM 64 bytes 79 bytes 80 bytes 128 bytes 256 bytes 511 bytes 512 bytes 1024 bytes master 1062564.71k 775113.11k 1069959.33k 1411716.28k 1653114.86k 1585981.16k 1973683.03k 2203214.08k master+patch 1062729.28k 771915.11k 1103883.42k 1458665.43k 1708701.20k 1647060.84k 1975571.80k 2204038.42k diff 0% 0% 3% 3% 3% 4% 0% 0% revert d6e428 1055290.03k 773448.92k 1117411.97k 1441478.57k 1695698.52k 1634598.04k 1981851.65k 2196680.36k CLA: trivial Reviewed-by: Tomas Mraz <tomas@openssl.org> Reviewed-by: Paul Dale <pauli@openssl.org> (Merged from https://github.com/openssl/openssl/pull/17984)
OpenSSL is a robust, commercial-grade, full-featured Open Source Toolkit for the Transport Layer Security (TLS) protocol formerly known as the Secure Sockets Layer (SSL) protocol. The protocol implementation is based on a full-strength general purpose cryptographic library, which can also be used stand-alone.
OpenSSL is descended from the SSLeay library developed by Eric A. Young and Tim J. Hudson.
The official Home Page of the OpenSSL Project is www.openssl.org.
The OpenSSL toolkit includes:
libssl an implementation of all TLS protocol versions up to TLSv1.3 (RFC 8446).
libcrypto a full-strength general purpose cryptographic library. It constitutes the basis of the TLS implementation, but can also be used independently.
openssl the OpenSSL command line tool, a swiss army knife for cryptographic tasks, testing and analyzing. It can be used for
Source code tarballs of the official releases can be downloaded from www.openssl.org/source. The OpenSSL project does not distribute the toolkit in binary form.
However, for a large variety of operating systems precompiled versions of the OpenSSL toolkit are available. In particular on Linux and other Unix operating systems it is normally recommended to link against the precompiled shared libraries provided by the distributor or vendor.
Although testing and development could in theory also be done using the source tarballs, having a local copy of the git repository with the entire project history gives you much more insight into the code base.
The official OpenSSL Git Repository is located at git.openssl.org. There is a GitHub mirror of the repository at github.com/openssl/openssl, which is updated automatically from the former on every commit.
A local copy of the Git Repository can be obtained by cloning it from the original OpenSSL repository using
git clone git://git.openssl.org/openssl.git
or from the GitHub mirror using
git clone https://github.com/openssl/openssl.git
If you intend to contribute to OpenSSL, either to fix bugs or contribute new features, you need to fork the OpenSSL repository openssl/openssl on GitHub and clone your public fork instead.
git clone https://github.com/yourname/openssl.git
This is necessary, because all development of OpenSSL nowadays is done via GitHub pull requests. For more details, see Contributing.
After obtaining the Source, have a look at the INSTALL file for detailed instructions about building and installing OpenSSL. For some platforms, the installation instructions are amended by a platform specific document.
Specific notes on upgrading to OpenSSL 3.0 from previous versions can be found in the migration_guide(7ossl) manual page.
The manual pages for the master branch and all current stable releases are available online.
There is a Wiki at wiki.openssl.org which is currently not very active. It contains a lot of useful information, not all of which is up to date.
OpenSSL is licensed under the Apache License 2.0, which means that you are free to get and use it for commercial and non-commercial purposes as long as you fulfill its conditions.
See the LICENSE.txt file for more details.
There are various ways to get in touch. The correct channel depends on your requirement. see the SUPPORT file for more details.
If you are interested and willing to contribute to the OpenSSL project, please take a look at the CONTRIBUTING file.
A number of nations restrict the use or export of cryptography. If you are potentially subject to such restrictions you should seek legal advice before attempting to develop or distribute cryptographic code.
