Hi all:

I am trying to utilize Crypt::OpenSSL::RSA perl module that is called  
from  
within the the http\_perl\_module handler. The interesting part is that if  
I  
use this module from a strait perl script then it works fine but when I  
call  
from the handler in nginx then it fail nginx’s sanity test check.  
Hopefully  
someone can shed some light here. I suspect  
/usr/lib/perl/5.12.4/auto/Crypt/OpenSSL/RSA/RSA.so to be the culprit  
somewhere.

First, I created two perl scripts as mentioned at  
[Encrypting Sensitive Data with Perl - Stuff... And Things...](http://stuff-things.net/2007/05/02/encrypting-sensitive-data-with-perl/).  
Here is the output from these two scripts, thus indicating that Perl  
modules  
installed are sane and complete …

Let me know if any additional piece of info is needed.

Thanks.
