[xmlsec] [xmlsec]Questions about template file

[Aleksey Sanin]

It looks like you have problems with OpenSSL library. Most common
problem on Windows is mixed runtime libraries:

http://www.openssl.org/support/faq.html#PROG2

If you will check this and everything is ok then I would suggest to add
ERR_print_errors_fp(stderr);
call to the end of your program to see what was the last OpenSSL error.
