Wallet Address hash generation

[rklz]

Hi, im using this tutorial https://en.bitcoin.it/wiki/Technical_background_of_version_1_Bitcoin_addresses#How_to_create_Bitcoin_Address to understand how to creat bitcoin wallet addresses.

But, for example, if u start from step 5 and hash this string 445C7A8007A93D8733188288BB320A8FE2DEBD2AE1B47F0F50BC10BAE845C094 with sha 256 again the result is:

7760845DCFD8C366AE89620BE2F368D255D710BC7493628CA0DCDED9CA476E5A and not D61967F63C7DD183914A4AE452C9F6AD5D462CE3D277798075B107615C1A8A30 like the step 6 shows.

Where is my error? I cant' figure this out.


To hash with sha 256 im using: http://www.xorbin.com/tools/sha256-hash-calculator
or

NodeJS: var hash = crypto.createHash('sha256').update(p).digest('hex');

(same results)

Thanks in advance!

The problem is your tool.   The tool you are using is hashing the input as "text".  Bitcoin public keys are byte arrays.  We may represent them as a hex values but you need to be hashing the actual bytes (i.e "0x77" is the value 119 not two numeric digits seven and seven).

You need a tool which hashes the bytes.  Here is one.   It supports RIPEMD160 as well so you can walk through the example from the beginning.

This is a common mistake. I admit when I first did this I was baffled by the different results. The problem is indeed the online tool. In fact for the last 3 years I've wondered why nobody made an online SHA256 hashing tool that has the option to convert the HEX to actual binary and then hash it.

The tool I linked does (and it outputs RIPEMD-160 was well).

Thanks you so much for your help guys!
