David A. Harding 2f0d7d8c3a Revert CC-BY-SA material added since the second edition
The commit ab5ae32bae is the last commit
for the second edition, so all changes since then are dropped except for
several commits for the third edition authored by Andreas Antonopoulos.

No attempt is made to remove CC-BY-SA or other licensed content present
in the already-published first or second editions.

This revert may itself be reverted for versions of the book published
under CC-BY-SA.

# example of iterating a nonce in a hashing algorithm's input

# calculate the SHA-256 hash of the input (text+nonce)
hash_data = hashlib.sha256(input_data).hexdigest()
