class twisted.internet._sslverify._ChooseDiffieHellmanEllipticCurve: (source)

View In Hierarchy

Chooses the best elliptic curve for Elliptic Curve Diffie-Hellman key exchange, and provides a configureECDHCurve method to set the curve, when appropriate, on a new OpenSSL.SSL.Context.

The configureECDHCurve method will be set to one of the following based on the provided OpenSSL version and configuration:

ParametersopenSSLVersionThe OpenSSL version number.
openSSLlibThe OpenSSL cffi library module.
openSSLcryptoThe OpenSSL crypto module.

Method _configureOpenSSL110 OpenSSL 1.1.0 Contexts are preconfigured with an optimal set of ECDH curves. This method does nothing.
Method _configureOpenSSL102 Have the context automatically choose elliptic curves for ECDH. Run on OpenSSL 1.0.2 and OpenSSL 1.1.0+, but only has an effect on OpenSSL 1.0.2.
Method _configureOpenSSL101 Set the default elliptic curve for ECDH on the context. Only run on OpenSSL 1.0.1.
Method _configureOpenSSL101NoCurves No elliptic curves are available on OpenSSL 1.0.1. We can't set anything, so do nothing.

def _configureOpenSSL110(self, ctx): (source)

OpenSSL 1.1.0 Contexts are preconfigured with an optimal set of ECDH curves. This method does nothing.

ParametersctxOpenSSL.SSL.Context
def _configureOpenSSL102(self, ctx): (source)

Have the context automatically choose elliptic curves for ECDH. Run on OpenSSL 1.0.2 and OpenSSL 1.1.0+, but only has an effect on OpenSSL 1.0.2.

ParametersctxThe context which . (type: OpenSSL.SSL.Context)
def _configureOpenSSL101(self, ctx): (source)

Set the default elliptic curve for ECDH on the context. Only run on OpenSSL 1.0.1.

ParametersctxThe context on which to set the ECDH curve. (type: OpenSSL.SSL.Context)
def _configureOpenSSL101NoCurves(self, ctx): (source)

No elliptic curves are available on OpenSSL 1.0.1. We can't set anything, so do nothing.

ParametersctxThe context on which to set the ECDH curve. (type: OpenSSL.SSL.Context)
