This 256-bit number is the _hash_ or _digest_ of the phrase and depends on every part of the phrase. Adding a single letter, punctuation mark, or any character will produce a different hash. <<sha256_example1>> shows the result of calculating the hash of +"I am Satoshi Nakamoto"+: +5d7c7ba21cbbcd75d14800b100252d5b428e5b1213d27c385bc141ca6b47989e+. This 256-bit number is the _hash_ or _digest_ of the phrase and depends on every part of the phrase. Adding a single letter, punctuation mark, or any other character will produce a different hash.
Now, if we change the phrase, we will expect to see completely different hashes. Let's try that by adding a number to the end of our phrase, using the simple Python scriptin <<sha256_example_generator>>.
