Add support for SOCKS5 proxy (or audit for 'usewithtor')
Add support for SNI:
    http://en.wikipedia.org/wiki/Server_Name_Indication
Update man page
Add tests for a given set of hosts that are known to be interesting
Add STARTTLS support for LDAP:
    http://www.rfc-editor.org/rfc/rfc2830.txt
Make a Debian package
Merge the Windows port into tip: http://code.google.com/p/sslscan-win/
Send diff from 1.8.2 to the upstream developer
Ensure that output is highlighted for dangerous ciphers (blink, blink)
    Throw up sirens if ssl2 is enabled
    ciphers from the LOW/EXP/eNULL category are supported for any protocol
    renegotiation is allowed on tlsv1 (maybe check if TRACE is supported if it's an http server)

Fix segfault when working with OpenSSL 1.0.0a:

    Program received signal SIGSEGV, Segmentation fault.

        (gdb) bt

We should explictly check for things that may be NULL; it is likely the cause
of the above error.
