(keeping TOFU style to keep thread consistent).

You can also just use the cipher-list configuration option string
that an OpenSSL 1.0.x should allow passing to OpenSSL.

So if I’m using 1.0.2, and want to deprecate 3DES, I need to do that as part of my build?

OK.  Are the 3DES CBC ciphers still part of DEFAULT?

Those ciphers are triple-DES, not single-DES. (The "CBC3" gives it away ... well, not exactly.) The single-DES ciphers were removed in release 1.1.0 (they are included in the "40 and 56 bit cipher support removed from libssl" item in the release notes), though the raw crypto primitives remain in libcrypto.

    Has DES been deprecated in OpenSSL?  If so, what release?  In
    particular the following ciphers

          0.22 EDH-RSA-DES-CBC3-SHA

        192.13 ECDH-RSA-DES-CBC3-SHA
