What is the difference between "-p 80" and "-http"?

The flag "-p 80" tells CryPing to ping port 80, which is the port used for HTTP requests. The flag "-http" tells CryPing to ping using HTTP. Both use the same port, but the behaviour is different.

The flag "-p 80" tells CryPing to simply check whether a connection can be made to port 80 and how long it takes to complete the connection, e.g.:

This shows whether something is listening on port 80, but without any requirement as to what is listening on that port.

The flag "-http" tells CryPing to check whether it can connect to the HTTP server, and how long it takes to complete the connection, e.g.:

So in this case it is testing that what is listening on port 80 does appear to be a web/HTTP server.

So, in summary "-p 80" checks whether something is listening on port 80 but it does not matter what is listening, whereas "-http" (which also connects to port 80") checks that there is an HTTP server listening.

How do you uninstall CryPing?

CryPing is a command line utility, it does not come with either an install program or with an uninstall program. If you no longer require CryPing then simply delete it, nothing else is required.
