[PHP] Re: Delay at first use of OpenSSL functions

[M. Sokolewicz]

well, since it's the openSSL library that's gathering it, that means ou 
can't control it with PHP itself. If you want to somehow change that 
process, either modify the library, or (if it's changable via the PHP 
extension,) modify the PHP extension for openSSL. Point is, there isn't 
(AFAIK/AFAICS) no way to do it VIA php.

possible to make it work faster? May be it can gather entropy only 
once (not every time script executes).
In the same script OpenSSL gather entropy only at first function call,
 then it can execute other functions very fast, so why can't it 
perform this process once not per script execution, but per hours, or 
let's say once per PHP libraries load in memory? If it can use the 
same entrophy for many functions, why it need to gather it every time 
when script run?

didn't you read what wez said? they're gathering entropy... you 
*can't* 

(and shouldn't want to) prevent that.

Hello, Gents,
When I use any OpenSSL encryption/decryption function (like
openssl_seal, openssl_open, openssl_public_encrypt,
openssl_private_decrypt, etc.) it takes very long time to execute,
 

when
it has been called in a first time. After that other function 
calls
performs very fast in the same script.

Not a php bug; the openssl libraries are gathering entropy on 
that 

first
hit.
How can I prevent this? All scripts executes a second longer, if 
there are any OpenSSL function.
Reproduce code:
---------------
$btime = microtime(true);
openssl_seal('Some information', $sealed, $ekeys, 
array(openssl_get_publickey('file://C:\512.pub')));
echo 'Time:  '.(microtime(true) - $btime);
$btime = microtime(true);
openssl_seal('Some information', $sealed, $ekeys, 
array(openssl_get_publickey('file://C:\1024.pub')));
echo '<br>Time:  '.(microtime(true) - $btime);
Expected result:
----------------
Time: 0.00************
Time: 0.00075888633728
Actual result:
--------------
Time: 0.969028949738
Time: 0.00075888633728
