How to unambiguously determine that a string is hashed?

Question

Python

Greetings.

Moved URL hashing into a separate function to search for matches in the database. I want to handle the situation when the input of this function is not the original URL, but an already hashed string, so that the function does not hash it again by accident.

Checking for the presence of a protocol (https or http) or a zone (.com, .ru) in a string does not seem like a good idea to me, because it is impossible to describe all possible URL options (for example, relative paths will not work at all).

If you try to parse the hash from the URL using urllib.parse.urlparse, the result is:

ParseResult(scheme='', netloc='', path='d8058d63868cb6d89211e6ec5a12ccf8', params='', query='', fragment='')

Share how you would solve such a problem?

import validators
validators.url("http://google.com")

Answer 2

Fixed length and characters only 0-9 and af
