What’s a hash function? In a more concrete example, this can be used to take a sequence of letters of any length as input — what we call a string — and return a sequence of letters of a fixed length.

Whether the input string is a single letter, a word, a sentence, or an entire novel, the output — called the digest — will always be the same length.

When you type in your password to log in, the same hash function is run on the word you’ve entered, and the server checks whether the result matches the stored digest. Simple hash functions in Python You can experiment with hash values using Python, a programming language installed on Mac and Linux operating systems by default. This tutorial will assume you’re using some version of either OS X or Linux, as using Python on Windows is more complicated.

This will put you into the Python REPL, an environment where you can try out Python commands directly as opposed to writing a programme in a separate file. To run it, put a string in between the parentheses in quotation marks, eg: You will see that calling the hash function on the same string will always generate the same hash, but adding or changing one character will generate a completely different hash value: In bitcoin mining, the inputs for the function are all of the most recent, not-yet-confirmed transactions along with some additional inputs relating to the timestamp and a reference to the previous block.

In the code example above, we’ve already seen that changing a small part of the input for a hash function results in a completely different output. You can use your returns to purchase more plans or make a profit by selling your bitcoins.
