Description:
------------
Openssl doesn't see al available ciphers.
In order to not get bored, please read the last part, and then, if you are still 
not bored, you can read following part, in order to understand how to get GOST 
ciphers in PHP.

Missing cipher is GOST R 34.10-2001.

BORING PART:
I have an fresh upstream OpenSLL, which now is by default built with GOST 
encryption. I want to use GOST encryption (actually, I have to use it, because 
I'm from Russia, and FSB/KGB/God knows who is forcing to use it). OpenSSL > 
1.0.0 is built with GOST encryption, but in order to actually enable it, you 
have to use a configuration file which mentions it. This is the first problem, 
still unresolved in the PHP, howevere there are several workarounds (all of the 
contail OPENSSL_config() call added somewhere).

I have a curl from upstream built with OPENSSL_config() call, and a curl PHP 
module loaded before openssl module (so, no openssl modifuication is needed).

NOT SO BORING PART:

Why I think it's missing:

Because openssl has it:

/usr/local/openssl/bin/openssl ciphers aGOST01
GOST2001-GOST89-GOST89:GOST2001-NULL-GOST94

(according to its manual - "aGOST01 - cipher suites
using GOST R 34.10-2001 authentication.")

Curl also has it:

/usr/local/curl/bin/curl --engine gost --ciphers GOST2001-GOST89-GOST89
https://google.com
curl: (35) error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3
alert handshake failure

I got a failure, but when the non-existent cipher suite is used, the
error is different:

/usr/local/curl/bin/curl --engine gost --ciphers GOST2001-GOST89-GOST666
https://google.com
curl: (59) failed setting cipher list

So, openssl has it, curl has it, but for some reason php doesn't.
openssl_get_md_methods() shows a couple of GOST digest but not GOST R
34.11-94:

array(30) {
  [0]=>
  string(3) "DSA"
  [1]=>

  [27]=>
  string(6) "sha384"
  [28]=>
  string(6) "sha512"
  [29]=>
  string(9) "whirlpool"

The code 

$encres = openssl_digest("123", "GOST R 34.11-94");
echo $encres;

gives this:

5ef18489617ba2d8d2d7e0da389aaa4ff022ad01a39512a4fea1a8c45e439148

And the code:

encres = openssl_digest("123", "GOST R 34.10-2001");
echo $encres;

gives this:

PHP Warning:  openssl_digest(): Unknown signature algorithm in 
/home/emz/ciphers.php on line 6

Test script:
---------------
<?php
        var_dump(openssl_get_md_methods());
        var_dump(hash_algos());
        $encres = openssl_digest("123", "GOST R 34.10-2001");
        echo $encres;
?>

Expected result:
----------------
I expect GOST R 34.10-2001 to be shown in the cipher list and openssl_digest() 
gives me encrypted string.


Actual result:
--------------
In fact, GOST R 34.10-2001 is not shown in the output of the 
openssl_get_md_methods(), and openssl_digest() is giving me the error:

PHP Warning:  openssl_digest(): Unknown signature algorithm in 
/home/emz/ciphers.php on line 6
