-v increase verbosity
-a test all known ciphers individually at the end
-json output results in json format
Use one of the options below:
-a | --allciphers Test all known ciphers individually at the end.
-b | --benchmark Activate benchmark mode.
-h | --help Shows this help text.
-j | --json Output results in JSON format.
-o | --openssl path/to/your/openssl binary you want to use.
-v | --verbose Increase verbosity.
The rest of the arguments will be interpreted as openssl s_client argument.
This enables checking smtp/imap/pop3/ftp/xmpp via -starttls
example: $0 -starttls xmpp jabber.ccc.de:5222
OpenSSL path can be changed in the OPENSSLBIN variable
Benchmarking can be enabled in the DOBENCHMARK variable
