Binaries

Some people have offered to provide OpenSSL binary distributions for selected operating systems. The condition to get a link here is that the link is stable and can provide continued support for OpenSSL for a while.

Note: many Linux distributions come with pre-compiled OpenSSL packages. Those are already well-known among the users of said distributions, and will therefore not be mentioned here. If you are such a user, we ask you to get in touch with your distributor first. This service is primarily for operating systems where there are no pre-compiled OpenSSL packages.

Third Party OpenSSL compatible engines

Product	Description	URL
Intel® QuickAssist Technology engine	Intel® QuickAssist Technology (http://www.intel.com/content/www/us/en/embedded/technology/quickassist/overview.html) provides acceleration for a number of cryptographic algorithms. QAT_engine adds support for Intel® QuickAssist Technology to OpenSSL-1.1.0 via the ENGINE framework. The definitive list of algorithms exposed into OpenSSL (a subset of those supported in the device) is defined on the associated github page.	https://github.com/01org/QAT_Engine
ATECCX08 engine	Support for the Atmel ATECC508A (http://www.atmel.com/devices/ATECC508A.aspx) hardware to provide secure key storage, ECC cryptographic calculations for the ECC NIST P-256 curve, and FIPS certified hardware Random Number Generator.	https://github.com/AtmelCSO/cryptoauth-openssl-engine
GOST engine	A reference implementation of the Russian GOST crypto algorithms for OpenSSL. The presence of this engine also enables the built-in OpenSSL support for GOST TLS ciphersuites. (Note: this engine is for OpenSSL version 1.1.0 and above. Previous versions of OpenSSL used a built-in GOST engine)	https://github.com/gost-engine/engine
