RE: Securing Z39.50 & SSL

Thanks,

The TLS RFC certainly does seem to have taken large chunks of the SSL3
document, but what made me think that TLS was a little more than an IETF
rebadge of SSL3 was the opening comment "The differences between this
protocol and SSL 3.0 are not dramatic, but they are significant enough that
TLS 1.0 and SSL 3.0 do not interoperate (although TLS 1.0 does incorporate a
mechanism by which a TLS implementation can back down to SSL 3.0)". However
at this point I must defer to the experts to elaborate on what these
differences are.

Since STunnel works on SSLeay/OpenSSL (STunnel basically provides the proxy
code relying on SSLeay or OpenSSL libraries to do the encryption stuff), I
would presume that it would also support TLS.
