You can't use an ordinary "telnet" tool - as you've discovered, it
doesn't speak SSL - but the OpenSSL library does have an equivalent
tool, s_client, designed for exactly what you're trying to do:
"telnetting" to an encrypted server for testing.


You presumably want something like this command:

s_client -connect localhost:443
