[Perhaps I ought to know this already, but...] RFC 2246 says "The differences between [TLS 1.0] 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)". To an unpractised eye, not used to the line-by-line collation of long texts, the two specifications seem pretty well identical. What *are* the important differences? ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
