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. Basically just a simple GUI for parts of sslinfo.
npm install -g ssl-peeker
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.
