sir,
I had made some modifiactions to the
programs(client/server programs) that are given in the
"opensslxxx/demos/ssl" directory.
Still iam getting errors while executing those
programs.
Here iam mentioning the client & server programs and
errors that iam getting.
-------------------------------------------------------
Client program( as in /demos/ssl)

void main ()

int err;
int sd;
struct sockaddr_in sa,ca;

CHK_NULL(ctx);
CHK_SSL(err);
sd = socket (AF_INET, SOCK_STREAM, 0);
CHK_ERR(sd, "socket");
memset (&sa, '\0', sizeof(ca));
ca.sin_family = AF_INET;

err = connect(sd, (struct sockaddr*)
&sa,sizeof(sa));
CHK_ERR(err,

ssl = SSL_new (ctx); CHK_NULL(ssl);
SSL_set_fd (ssl, sd);
err = SSL_connect (ssl); CHK_SSL(err);
err = SSL_write (ssl, "Hello!", strlen("Hello!"));
CHK_SSL(err);

CHK_SSL(err);
buf[err] = '\0';
printf ("Got %d chars:'%s'\n", err, buf);
SSL_shutdown (ssl);
close (sd);
SSL_free (ssl);
SSL_CTX_free (ctx);
}

you."));
CHK_SSL(err);
close (sd);
SSL_free (ssl);
SSL_CTX_free (ctx);
}
-------------------------------------------------------
Errors those iam getting
-------------------------------------------------------
1426:error:0D06B078:asn1 encoding routines:ASN1_ get
_object :header too long:asn1_lib.c:139:
1501:error:0D09F006:asn1 encoding routines:d2i_X509:
bad get asn1 object call :x_x509.c:101:address=
135057040 offset = 0
1501:error:1407E00B:SSL routines:SSL2_SET_CERTIFICATE:
X509 lib:s2_clnt.c:906:(I think this is the main
error)
-------------------------------------------------------
Shall you suggest me how to eliminate those errors.
Thanks for your consideration
