James E. King III updated THRIFT-3165:
--------------------------------------
    Summary: Disable unsafe TLSv1.0 and TLSv1.1 by default  (was: Remove TSSLSocket::SSLProtocol and require subclass of SSLContext to control TLS negotiation)

>             Project: Thrift
>          Issue Type: Improvement
>          Components: C++ - Library
>    Affects Versions: 0.9.2
>            Reporter: James E. King III
>            Priority: Major

> Thrift provides an SSL implementation and implements some best practices (for example, SSLv2 and SSLv3 are disabled). The current mechanism in the C++ library to control the protocol negotiation is unnecessarily complex.
> The current behavior is to use an enumeration to set the protocol level. The methods these call are deprecated in OpenSSL 1.1 and do not provide the desired control.
> The proposed new behavior is to:
>  * Remove SSLProtocol
>  * Require the consumer to subclass SSLContext and call SSL_CTX_set_option to disable certain behaviors, like negotiation protocol levels.
> For example the following SSLContext subclass will ensure connections are at TLSv1_2 or later:
> {noformat}
> class SSLContextOnlyTLSv12OrLater : public SSLContext
> {
>   public:
>     SSLContextOnlyTLSv12OrLater() : SSLContext()
>     {
>         // SSLContext already disables SSLv2 and SSLv3
>         SSL_CTX_set_options(get(), SSL_OP_NO_TLSv1); // This is TLSv1_0
>         SSL_CTX_set_options(get(), SSL_OP_NO_TLSv1_1);
>     }
> };
> {noformat}
