Openssl SSL_accept() fails with Unknown Protocol
Edit -
I changed
method = SSLv23_server_method(); to
method = TLSv1_2_server_method()
;
Now SSL_accept() gives me back a wrong version number error.
error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number:s3_pkt.c:386:
When I listed the SSL and TLS versions in use on my system -
openssl ciphers -v | awk '{print $2}' | sort | uniq
SSLv3
TLSv1.2
What am I missing here ?
@jww -> Tagging you coz I noticed you answered a few qs related to openssl. Hope you dont mind
I am running into an issue with SSL_accept() in my server code. I am using openssl 1.0.2g. After much research, I could not find the real reason for the error.
Here is my server code -
open socket , bind to socket, listen on socket
initialize SSL context and libraries. Load certificate and Private key files
{
SSL_load_error_strings();
ERR_load_BIO_strings();
SSL_library_init();
OpenSSL_add_all_algorithms();
const SSL_METHOD *method;
method = SSLv23_server_method();
ctx = SSL_CTX_new(method);
if (SSL_CTX_use_certificate_file(ctx, ccrt, SSL_FILETYPE_PEM) <= 0) {
ERR_print_errors_fp(stdout);
}
if (SSL_CTX_use_PrivateKey_file(ctx, ckey, SSL_FILETYPE_PEM) <= 0 ) {
ERR_print_errors_fp(stdout);
}
pselect() waits on any incoming connections or any reads on existing connections
if new connection - accept() the connection and add to the pselect FD_SET and return
if existing connection, there is something to read so do the following {
SSL *ssl;
if ( !ctx )
{
return 0;
}
ssl = SSL_new(ctx);
SSL_set_fd(ssl, soc);
int ret = SSL_accept(ssl); --> FAILS
if (ret <= 0) {
ERR_print_errors_fp(stdout);
return 0}
}
When the error queue is printed it shows -
error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol:s23_srvr.c:640:
Is this a version mismatch (Openssl 1.0.2g) ?
c++ encryption openssl tls1.2

But it looks like SSLv3 is disabled by default in 1.0.2g per this - launchpad.net/ubuntu/+source/openssl/1.0.2g-1ubuntu1. So I am confused as to which method I should be using for ubuntu 18.04
