How I can add extension with sequence value to CSR using openssl library?

I know how to add simple extension (oid + str), for example ``` nid = OBJ_create("1.2.3.4", "shortname", "long name"); ASN1_OCTET_STRING_set(os, "ext value", 9); ex = X509_EXTENSION_create_by_NID( NULL, nid, 0, os ); sk_X509_EXTENSION_push(exts, ex); ``` I want to learn how I can add extension wi

Problem with TLS handshake using OpenSSL library when data size exceeds buffer

Hi there, I am working on a TLS server at present, but am having problems with handshaking on occasion. The setup: * My TLS server sets up a TLS context, and three BIOs; an SSL bio, and a BIO pair (application and socket). * A remote party attempts to start a TLS handshake wi

Re: How to implement DH algorithm using openSSL library?

I also have a problem in sending the pub_key to peer. As I am using DH_generate_parameters to generate prime and generator and DH_generator_key for generating the public key , I have to send the prime, g and pub_key to the peer. Is there any function to do this?? Thanks in advance. Yamini. On Fr

How to implement DH algorithm using openSSL library?

Hello!! I am trying to implement Diffe-Hellman Key exchange protocol between Client and server. I am using openSSL dh.h library for that. The problem is how to send the publickey generated by DH_generate_key() function to client/server. My idea is to get the shared secret which I can use for fur

Memory leak while using OpenSSL library

Hi all I use libcsoap 1.1.0 library, to call some HTTP/HTTPS web services. libcsoap in turn uses OpenSSL for authenticating the secure sessions (HTTPS). Both HTTP and HTTPS web service are functioning well and I get the proper response in both cases. But I found many memory leaks when I try to ca
