Hi, I suggested one such implementation in mongoose opensource web server You can check it in . https://groups.google.com/forum/#!msg/mongoose-users/IAzYHF0do-I/INc_VmLAe6gJ This is the function I added let me know if it is useful. static int CheckSSL(int nSocket) { /* taken from s23_svr.c int ssl23_get_client_hello(SSL *s) of openssl */ char szData [12] ; int nRet = 0 ; int n; memset ( szData, 0, sizeof(szData)); n = recv ( nSocket, szData, 11, MSG_PEEK ) ; if (n > 2) { if((szData[0] & 0x80) && (szData[2] == 1)) // SSL2_MT_CLIENT_HELLO { // SSLv2 nRet = 1; } else if(n > 9) { if ((szData[0] == 22 ) && // SSL3_RT_HANDSHAKE (szData[1] == 0x03) && // SSL3_VERSION_MAJOR (szData[5] == 1) && // SSL3_MT_CLIENT_HELLO ((szData[3] == 0 && szData[4] < 5) || (szData[9] == szData[1]))) { // SSLv3 nRet = 1; } } } return nRet; } On Sat, Apr 4, 2015 at 5:10 AM, James Cloos <cloos at jhcloos.com> wrote: > >>>>> "JR" == Joris Van Remoortere <joris at mesosphere.io> writes: > > JR> I would like to ask your opinion and advice on accepting HTTP / HTTPS > JR> connections on the same port. > > IPP support both w/ and w/o tls on port 631. > > Cups handles it like this: > > http://www.pwg.org/archives/ipp/2014/017906.html > > -JimC > -- > James Cloos <cloos at jhcloos.com> OpenPGP: 0x997A9F17ED7DAEA6 > _______________________________________________ > openssl-users mailing list > To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users > -------------- next part -------------- An HTML attachment was scrubbed...
