I am testing Block hashing algorithm from
https://en.bitcoin.it/wiki/Block_hashing_algorithm
code in Python and PHP + sha256 library
+ code in plain C from
http://pastebin.com/bW3fQA2a
unfortunately block header parameters from
http://blockexplorer.com/block/00000000000000001e8d6829a8a21adc5d38d0a473b144b6765798e61f98bd1d
don't come in sha256 hashing format
since I need Unix time conversion for >>> Time?: 2011-05-21 17:26:31

the same problem with time parameter.
Any idea how to download block headers file
as 6 parameter input into my block hashing algorithm in Javascript ?

Hi,
Block hashing in Javascript - Could you help me with implementation ?
I am looking for block hashing in Javascript demo, reading input parameters from Blockchain ( 6 parameters)
saved to database and run off-line, as demo for students to verify the calculated nonces were correct from the first block.
Looking for hashing algorithm ( sha256 in Javascript already works fine)
and 6 input parameters as datafile.
Any idea ?
