It is widely used by Internet servers, including the majority of HTTPS websites. We But I am still confused about this: what does Au=ECDH mean for a cipher such as ECDH-ECDSA-AES256-SHA. Applications using OpenSSL may be affected by this vulnerability if the version of OpenSSL they use supports ephemeral ECDH Everyone should be able to check signatures. Newer applications should just call: SSL_CTX_set_ecdh_auto(ctx, 1); and they will automatically support ECDH I am running openssl 1.

I've gone through all the unit tests included in the OpenSSL package. Additionally, it will use pkg-config on Unix-like systems to find the system installation. It is the basis for the OpenSSL implementation of the Elliptic Curve 1.
