There are also complete hash databases on the internet. They usually
reverse-map hash values to most common values found in dictionaries.
Here is an example:
>>> import hashlib
>>> h = hashlib.md5("test")
Then you go here:
There are many other databases like this, search for them with "md5
search" or "sha1 database" etc.
