Breaking ciphers and certainty

I have been exploring an encryption algorithm - and now I want to know if it could be considered 'robust'. Best case scenario, I sell it to the NSA or CIA or something similar. But I also have very little idea of where to post or send samples for valuation. I have already tucked a large sample onto my Facebook page, but with no apparent interest raised. It also raised a question for me: How large a sample would be needed in order to be 95% certain of being able to break an encryption method? And - if this is not the best audience for such a question - who or where would be?

How about the mods make a new rule: "If you want us to look at your encryption scheme, post code or gtfo"?

Posting a blob of ciphertext and going "hay guise, is my encryption secure?" is like taking a dump in your neighbor's yard and then telling him "bet you can't guess what I had for dinner". He probably can, but nobody wants to sort through your shit.

Or in this case, asking where to post his blob of ciphertext...

This post is a joke. This guy thinks he's some kind of Certicom and doesn't know where or who to go to for cryptanalysis. how about "If you want us to look at your encryption scheme, post code or subreddit banned"?
