The SSL/TLS protocols only work with streams. You could use datagrams to implement streams (look at BIO pairs for how to implement this on top of OpenSSL), but if you want the protocol to tolerate packet loss, you can't use SSL or TLS. -- Bodo Möller <[EMAIL PROTECTED]> PGP http://www.informatik.tu-darmstadt.de/TI/Mitarbeiter/moeller/0x36d2c658.html * TU Darmstadt, Theoretische Informatik, Alexanderstr. 10, D-64283 Darmstadt * Tel. +49-6151-16-6628, Fax +49-6151-16-6036 ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
