Warning: Both RC4 and MD5 are INSECURE. They are susceptible to
practical attacks. Do not use them.

MD5 is already disabled by default. Real collisions have been produced,
and used to forge certificates in the wild; its use as an HMAC is also
strongly discouraged. It must never be used.

RC4 (both RC4-MD5, RC4-SHA and other RC4 ciphers) is a very old stream
cipher. It is thought some adversaries can already break it in real-
time; in the public literature, several serious weaknesses have already
been found (and at the time of writing, another one is on the way). An
RFC will shortly be published - see <https://tools.ietf.org/html/draft-
popov-tls-prohibiting-rc4-02> - entirely prohibiting the use of all RC4
ciphersuites in all circumstances. Some browsers are already in the
process of turning it off.

Please see the results at:
- https://www.ssllabs.com/ssltest/analyze.html?d=centinel1000.cardinalcommerce.com
- https://www.ssllabs.com/ssltest/analyze.html?d=inaturalist.org
which indicate that these sites have deep problems with their encryption.

centinel1000.cardinalcommerce.com seems to be run from an outdated
Windows Server 2003 using IIS/6.0 (which hits end-of-life in about a
year). It only offers insecure ciphersuites RC4-MD5 & RC4-SHA, and only
over SSLv3 (it is intolerant of modern TLS 1.2 connections). You will
see from the results that current versions of all mainstream browsers
already refuse to connect to it, and in particular I must be clear it is
NOT A BUG that curl and wget also refuse to do so - that is correct
behaviour and should be regarded as bad as if it offered only 'export'
ciphers. Its encryption is exploitably bad: I would consider it in
breach of PCI requirements.

inaturalist.com does not support TLS 1.2, uses RC4 (insecure) in
preference to other ciphersuites, and offers 1024-bit DHE which is
insecure. IE11 does the best it can there and connects with
TLS_RSA_WITH_AES_128_CBC_SHA (0x2f); this is susceptible to BEAST, but
not as bad as the above. The problem being reported by curl is that
inaturalist.com is intolerant of TLS 1.2. This is also NOT A BUG with
the client, but is a bug with the server. Some browsers retry with lower
protocol versions automatically (and should use the "downgrade" SCSV to
indicate this, as this is otherwise behaviour exploitable by an
attacker); curl and wget do not.

It is strongly likely that future versions of TLS libraries will
completely ignore requests to use these ciphersuites: libReSSL disables
it, and I think BoringSSL might too. At best, this is a stop-gap
measure, but you should be aware the problem does not lie with you here.
I suggest you contact the respective sites' security departments to
inform them their encryption is weak.

As this does not seem to be a bug in the client, I suggest closing this
one.

  This is in Ubuntu 14.04 Trusty and I have 'apt-get upgrade' and 'update-ca-certificate --fresh'
  Note that most/all of these have been tested in MacOSX OpenSSL 0.9.8y 5 Feb 2013 and Ubuntu 12.04 OpenSSL 1.0.1 14 Mar 2012

  I will attempt to compile or downgrade myself now.
