This directive appeared in versions 1.1.0 and 1.0.6.
Specifies a curve
for ECDHE ciphers.
When using OpenSSL 1.0.2 or higher, it is possible to specify multiple curves (1.11.0), for example:
ssl_ecdh_curve prime256v1:secp384r1;
The special value auto
(1.11.0) instructs nginx to use a list built into the OpenSSL library when using OpenSSL 1.0.2 or higher, or prime256v1
with older versions.
Prior to version 1.11.0, the prime256v1
curve was used by default.
