I've been deep in the weeds of sha256, with Python3, while working on a Python implementation of the DIY Bitcoin Private Key Project
In fact, if there's any coders here, maybe you could help me out:
I first want to get to grips with the Python sha256 function, so that I can move on to the more complex operation of generating the 24th BIP0039 seed word, for which I need the first 8 bits of the sha256 check sum that's derived by hashing the entire 256 bit key.
So, the basics first: I don't understand (as an example) why...
$ echo R | shasum -a 256 -t
... returns...
13b30eab8afdfab285103004686b2e6140ce53aa45a4f917341c740dfdb6e956
... while...
print(sha256('R'.encode('utf-8')).hexdigest())
... returns...
8c2574892063f995fdf756bce07f46c1a5193e54cd52837ed91e32008ccf41ac
Once I get this nailed down, I can move on the the more complex task.

My thanks to you both (a bit of a 'head slap' moment for me!).
The cli echo commend is in fact directly from the Bitcoinmagazine feature, so I'm now thinking that it's an incorrect method. Time will tell, because if the checksum is not correct, a Wallet such as Sparrow will not accept the 24 Word Seed. I know that the Electrum Wallet does not do that check (I've tried it), so any random collection of 24 BIP0039 Seed Words will work.
Thanks again; back to it :)
We had some more discussions around Pleb Garage and the future Pleb House. Capital Factory wants to work with us but I have a feeling it'll be hard for them to understand what we're trying to do.
Rewrote and reviewed my Bitcoin Seminar notes. Trying to make them stick.
Love it!
Tell me, if would, how does one embed a jpg (is it?) file, like you've done here?
I used a link to a hosting site, but it seems you're doing something different?
Okay; thanks.
I thought that that's what I'd done, but a 'hover' over the image I embedded, shows a link back to the hosting site, which doesn't happen with your embed.
I'll try again, the next time I need to do such an operation; I must have messed up somewhere.
Peace.
