Displaying "posthash" in the post...?

[smashtheqube]

How would I output the posthash of a post below a post right before the user's signature is shown? (just for kicks... I'm brainstorming about tieing some things together that way)

Are all post hashes unique?

[AN-net]

yes they are all unique as it is a mixture of userid, date, and user salt

why would u want to do this anyways? it serves no purpose to display
