[edit] Summary
A typical hash function at work. Note that the hash sums always are the same size, no matter how short or long the input is and also note that the hash sums look very different even when there are only slight differences in the input.
The hash sums seen here (in hexadecimal format) are actually the SHA-1 hash sums of those text examples.
