Have you tried to use the code without modifications using the same
certificate?
If you need to load the X509 certificate use following code. Moreover
you may find useful information to call these PEM routines in the manual
page(%man PEM).

<Code for loading certificate>
BIO *in;
if ((in=BIO_new_file(filename,"r")) == NULL)
{
printf("Error reading the file\n");
return -1;
}
/*Read certificate*/
PEM_read_bio_X509(in, &cert,NULL,NULL);
if(!cert)
{
printf("Error creating the certificate\n");
return -1;
}
BIO_reset(in);
BIO_free(in);
</Code for loading certificate>

kapuruge,
thanks a lot for helping. i tried the source code you gave me and
added some.
here's what I did:
AnsiString FName = ExtractFilePath(Application->ExeName) + "temp.crt";
X509 *xca=NULL;
char *xca2=NULL;
xca2 = FName.c_str();
xca = ReadCertificate(xca2);
BIO *out;
unsigned char *issuer, *result;
int n;
out = BIO_new(BIO_s_mem());
X509_NAME_print_ex(out, X509_get_issuer_name(xca), 0,0);
n = BIO_get_mem_data(out, &issuer);
result = (char *) malloc (n+1);
result[n]='\0';
memcpy(result,issuer,n);
BIO_free(out);
out = NULL;
AnsiString issuerTemp(reinterpret_cast<char *>(result));
ShowMessage(issuerTemp);
I tried displaying the issuer using the ShowMessage, but i returned an
empty message box. what did i do wrong?
thanks a lot

Macho,
You may use following code. Here cert is X509*.
Cheers,
Kaushalye
BIO *out;
unsigned char *issuer, *result;
int n;
out = BIO_new(BIO_s_mem());
X509_NAME_print_ex(out, X509_get_issuer_name(cert), 0,0);
n = BIO_get_mem_data(out, &issuer);
result = (char *) malloc (n+1);
result[n]='\0';
memcpy(result,issuer,n);
printf("Issuer : %s\n",result);
BIO_free(out);
out = NULL;
