Re: PEM_read_X509 and d2i_X509_fp problem.

2005-05-10 Thread Calista 
Yes, I have set up the call-backs exactly as in
crypto\threads\mttest.c

The problem seems to be going away when the replace
the 
fseek with fclose and fopen the file again. Does this
sound weird? (considering that all threads may be
executing this code simultaneously).

if(!(x509=d2i_X509_fp(fp, NULL))) {   
  
  fseek(fp, 0,SEEK_SET);
  x509 = PEM_read_X509( fp, NULL, NULL, NULL );
}

Did you set up your mutex call-backs needed by the library? See the  
man page for CRYPTO_set_locking_callback, et al for details.

PEM_read_X509 and d2i_X509_fp problem.

2005-05-06 Thread Calista 
The code below fails sometimes( it prints "error"). I
don't understand why. I have a multi threaded
application, and all the threads may be doing the
following code simultaneously. Are the functions
d2i_X509_fp and PEM_read_X509 thread safe?

The variables - x509, fp, cert_filename are local
non-static variables in the function.

The following is a code snippet.
if((fp = fopen (cert_filename, "r"))) {
   x509=NULL;
   if(!(x509=d2i_X509_fp(fp, NULL))) {  fseek(fp, 0,
SEEK_SET);
x509 = PEM_read_X509( fp, NULL, NULL, NULL );
   }
   
   if( !x509 ) {
  printf("error\n"); 
   }
}

Any help is greatly appreciated in this regard.
Thank you.
