Weibo of the simulation landing is a comparison pit, see a lot of great God on the Internet post, and I saw the microblog of the log when the JSON data: 1, found in the login when entering the account with Chrome can see there will be a prelogin such as the URL, after the URL will have a large number of random numbers. I tested, found that in the absence of random numbers in the case of the URL can also get the required severtime, nonce, and so on sev
that they are communicating with a real website, rather than a fraudulent website trying to lure them into entering their usernames and passwords. SSL performs this authentication by using an SSL certificate provided by a trusted authority such as VeriSign. The logic is as follows: VeriSign guarantees that the identity of the Bank's website is true. Because Internet Explorer trusts VeriSign, it also trusts the website. If you want to verify with VeriSign, you can click the VeriSign logo to perf

Almost all colleagues small brother help me pave the way, to my reference link, the realization of the theoretical method and knowledge, I only see the information, Knock code, error is also he helped me look at a step-by-step explanation to fix over. Well, a good one.OK, Idea:is to generate a random number placed in the URL, as a parameter pass, in the business request controller to verify that the nonce is consistent with the cache, and add a timest

The structure of the block header is as follows
So the algorithm can be expressed as
Block_header = version + Previous_block_hash + merkle_root + time + target_bits + nonce
to I in range (0, 2**32):
If sha256 (sha256 (Block_header))
