Title: ??: Please Help: Crypto library with Visual C++



Hi,

Thanks 
for your reply. I have tried, still the memory leak problem happens 
:)
and 
the whole application crashes

my 
code is like this:

BIO *bio, *b64;BIO 
*bio_out;char inbuf[128];int 
inlen;b64 = BIO_new(BIO_f_base64());bio = 
BIO_new_file("content.key", "rb"); bio_out = BIO_new_fp(stdout, 
BIO_NOCLOSE);bio = BIO_push(b64, bio);while ((inlen = 
BIO_read(bio, inbuf, 128))  0) {BIO_write(bio_out, inbuf, 
inlen);}

BIO_free_all(bio);

what I 
wish to do is, read the data from the file content.key 
and 
then decode the data 
and 
then convert the decoded data in to a char * (or perhaps to another new 
file)
but 
here what i do is just print out the decoded data :)

i am 
sorry to bother you that much.

pls 
forgive
and 
pls help if you have the time :D

thousand thanks. Wish you all the 
best.

Best

  oh 
  nothing do not be nervous
  i think 
  if you want to read data from a file 
  first 
  you must construct a 
  
  BIO * mbio = BIO_new_file(filename , "rb") object 
  
  then build another BIO* b64 =BIO_new(BIO_f_base64()); 
  then mbio = BIO_push(b64, 
  mbio); 
  
  all ok 
  ...
  read data from 
  
  while((inlen = 
  BIO_read(mbio, inbuf, strlen(message)))  0)
  {
  do as you 
  wish
  }// remember free all bio resource BIO_free_all(bio);
can this solve your problem?

HI :D 
Sorry to bother you again.


I 
think I have found the reason :)
it is 
because the Project setting is incorrect (thanks for your hints 
indeed)

I have 
to set the Code Generation (under tag C/C++), the "Use run-time library" to 
"Multithreaded DLL" :D

All 
the best.

  oh when application crash .. it normally beacause link mfc lib 
  problem
  you may try use mfc in shared dll or mfc instatic 
  dll
  it may ok..
  as for memory leak ..
  
  begin ..
  OpenSSL_add_all_algorithms();SSL_load_error_strings();
  
  your code...
  End:
  
  ERR_free_strings();EVP_cleanup();
  
  see u later...:)
