+Subject: [PATCH] [ruby/openssl] ssl: use ffdhe2048 from RFC 7919 as the
+ default DH group parameters
+
+In TLS 1.2 or before, if DH group parameters for DHE are not supplied
+with SSLContext#tmp_dh= or #tmp_dh_callback=, we currently use the
+self-generated parameters added in commit https://github.com/ruby/openssl/commit/bb3399a61c03 ("support 2048
+bit length DH-key", 2016-01-15) as the fallback.
+
+While there is no known weakness in the current parameters, it would be
+a good idea to switch to pre-defined, more well audited parameters.
+
+This also allows the fallback to work in the FIPS mode.
+
+The PEM encoding was derived with:
+
+	# RFC 7919 Appendix A.1. ffdhe2048
+	print OpenSSL::PKey.read(OpenSSL::ASN1::Sequence([OpenSSL::ASN1::Integer((<<-END).split.join.to_i(16)), OpenSSL::ASN1::Integer(2)]).to_der).to_pem
+	    FFFFFFFF FFFFFFFF ADF85458 A2BB4A9A AFDC5620 273D3CF1
