Function Test-SslOptions {
<#
.SYNOPSIS
This cmdlet is used to test the TLS protocols and ciphers available on a remote device
.DESCRIPTION
Define the TCP port and domain of a URL you want to check TLS availability on to return info on the TLS protocols available
.PARAMETER UrlDomain
Defines the FQDN, hostname, or IP address to make a TLS connection with
.PARAMETER Port
Defines the destination port to create a test TCP connection with using SSL
.EXAMPLE
Test-SslOptions -UrlDomain osbornepro.com -Port 443
.EXAMPLE
"writeups.osbornepro.com","osbornepro.com","btpssecpack.osbornepro.com","encrypit.osbornepro.com" | Test-SslOptions-Port 443
