ssl-peeker
Checks a host for SSL info, like who the certificate was issued to, who it was issued by, when it's valid, what protocols are enabled, and what ciphers are available.
Installation
npm install -g ssl-peeker
Usage
ssl-peeker <host> [port]
host is required. This is either the hostname or IP address whose SSL info you want to peek at.
port is optional. By default, HTTP/S runs on port 443, but in case that's not true for you, you can specify the port as well.
