However it is based on version 1.0.2 and I need to use OpenSSL 1.1.1. In the wiki they register the ECDH method by using the ENGINE_set_ECDH(ENGINE *e, ECDH_METHOD * ecdh) function but this function is not available with OpenSSL 1.1.1. I looked the documentation but i didn’t find the equivalent for version 1.1.1.
Sep 27, 2016 · Download OpenSSL for free. This project offers OpenSSL for Windows (static as well as shared). It supports: FIPS Object Module 1.2 and CAPI engine. openssl verify cert.pem If your "ca-bundle" is a file containing additional intermediate certificates in PEM format: openssl verify -untrusted ca-bundle cert.pem If your openssl isn't set up to automatically use an installed set of root certificates (e.g. in /etc/ssl/certs), then you can use -CApath or -CAfile to specify the CA. Provides an abstract base class that Elliptic Curve Diffie-Hellman (ECDH) algorithm implementations can derive from. This class provides the basic set of operations that all ECDH implementations must support. This is only with openssl 1.1 , with 1.0.x it works just fine. After some reading, i saw this change on OpenSSL: *) Change the ECC default curve list to be this, in order: x25519, secp256r1, secp521r1, secp384r1. [Rich Salz] Somehow openssl defaults to x25519 , and my certificates are using sect571r1, and passing ecdh-curve to openvpn does not
To generate a DH key pair, with the OpenSSL command-line tool, you have to do it in two steps: openssl dhparam -out dhparam.pem 1024 openssl genpkey -paramfile dhparam.pem -out dhkey.pem For an ECDH key pair, use this: openssl ecparam -out ecparam.pem -name prime256v1 openssl genpkey -paramfile ecparam.pem -out ecdhkey.pem
Mar 01, 2017 · OpenSSL is a very handy tool. Both on Linux and Windows. On both you can do all kinds of conversions and creations, but equally of use you can view cipher details that are supported. On … To generate a DH key pair, with the OpenSSL command-line tool, you have to do it in two steps: openssl dhparam -out dhparam.pem 1024 openssl genpkey -paramfile dhparam.pem -out dhkey.pem For an ECDH key pair, use this: openssl ecparam -out ecparam.pem -name prime256v1 openssl genpkey -paramfile ecparam.pem -out ecdhkey.pem Here is an example of a cipher list specification that requires authenticated empheral ECDH key agreement (ECDH), RSA for authentication and only cipher suites that are considered of "high" encryption: openssl s_client -cipher ECDH+aRSA+HIGH -connect example.com:443 What does this expand to? The openssl ciphers command can be used for this purpose: Jan 07, 2015 · In the IPS tab, click Protections and find the OpenSSL Ephemeral ECDH Cipher Suite Handshake Downgrade protection using the Search tool and Edit the protection's settings. Install policy on all Security Gateways. This protection's log will contain the following information: Attack Name: SSL Enforcement Violation.
OpenSSL can be used with pkcs11 engine provided by the libp11 library, and complemented by p11-kit that helps multiplexing between various tokens and PKCS#11 modules (for example, the system that the following was tested on supports: YubiHSM 2, YubiKey NEO, YubiKey 4, Generic PIV tokens and SoftHSM 2 software-emulated tokens).

For what it's worth, in OpenSSL 1.0.2, s_client now displays the curve name: $ openssl s_client -connect crypto.stackexchange.com:443 [] --- No client certificate CA names sent Peer signing digest: SHA512 Server Temp Key: ECDH, P-256, 256 bits --- SSL handshake has read 3436 bytes and written 443 bytes --- New, TLSv1/SSLv3, Cipher is ECDHE-ECDSA-AES128-GCM-SHA256 Server public key is 256 OpenSSL can be used with pkcs11 engine provided by the libp11 library, and complemented by p11-kit that helps multiplexing between various tokens and PKCS#11 modules (for example, the system that the following was tested on supports: YubiHSM 2, YubiKey NEO, YubiKey 4, Generic PIV tokens and SoftHSM 2 software-emulated tokens). I've scoured this website and the OpenSSL wiki pages, and done numerous internet searches, and I've come to the seemingly incredible conclusion that one cannot generate an ECDH shared secret key using a given public key and a given private key from the openssl command line.
