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;
