- Alert handling has been improved to better handle
- unexpected but valid messages and the implementation is
- also changed to avoid timing related issues that could
- cause different error messages depending on network
- latency. Packet handling was sort of broken but would
- mostly work as expected when socket was in binary mode.
- This has now been fixed.</p>

- All inet options are available in the new ssl

- <p>A new implementation of ssl is released as a alfa
- version in ssl-3.9 it will later replace the old
- implementation in ssl-4.0. The new implementation can be
- accessed by providing the option {ssl_imp, new} to the
- ssl:connect and ssl:listen functions.</p>
- <p>The new implementation is Erlang based and all logic
- is in Erlang and only payload encryption calculations are
- done in C via the crypto application. The main reason for
- making a new implementation is that the old solution was
- very crippled as the control of the ssl-socket was deep
- down in openssl making it hard if not impossible to
- support all inet options, ipv6 and upgrade of a tcp
- connection to an ssl connection. The alfa version has a
- few limitations that will be removed before the ssl-4.0
- release. Main differences and limitations in the alfa are
- listed below.</p>
-
- <list type="bulleted"> <item>New ssl requires the crypto
- application.</item> <item>The option reuseaddr is
- supported and the default value is false as in gen_tcp.
- Old ssl is patched to accept that the option is set to
- true to provide a smoother migration between the
- versions. In old ssl the option is hard coded to
- true.</item> <item>ssl:version/0 is replaced by
- ssl:versions/0</item> <item>ssl:ciphers/0 is replaced by
- ssl:cipher_suites/0</item> <item>ssl:pid/1 is a
- meaningless function in new ssl and will be deprecated in
- ssl-4.0 until it is removed it will return a valid but
- meaningless pid.</item> <item>New API functions are
- ssl:shutdown/2, ssl:cipher_suites/[0,1] and
- ssl:versions/0</item> <item>Diffie-Hellman keyexchange is
- not supported.</item> <item>Not all inet packet types are
- supported.</item> <item>CRL and policy certificate
- extensions are not supported.</item> <item>In this alfa
- only sslv3 is enabled, although tlsv1 and tlsv1.1
- versions are implemented and will be supported in future
- versions.</item> <item>For security reasons sslv2 is not

- <p>Because fopen() on Solaris 8 can't handle file

- problem has been worked around.</p>
- <p>The ssl application's port program used to use

- <p>Solaris/Sparc, 64-bit emulator: The SO_REUSEADDR
