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.

In particular any donations or payments to any of these organizations will not be known to, seen by, or in any way benefit the OpenSSL project.

Use these OpenSSL derived products at your own risk; these products have not been evaluated or tested by the OpenSSL project.

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
ISARA Radiate Solution Suite OpenSSL Connector	Commercially available engine and source code patch for OpenSSL 1.0.2 branch. The ISARA Radiate OpenSSL Connector lets you implement OpenSSL using quantum safe algorithms. ISARA Radiate (https://www.isara.com/isara-radiate/) gives you the cryptographic building blocks to create applications that will resist attacks by quantum computers.	https://www.isara.com/openssl/1/
BEE2EVP engine	Implements the Belarusian national cryptography: symmetric and public-key encryption, MAC, AEAD, hashing, digital signature. Encapsulates the Bee2 core cryptographic library into OpenSSL using the EVP interface.	https://github.com/bcrypto/bee2evp
