1st choice in hash regognition, cyberchef. Only told be that base64 valid. Ok then google for “base64 (few chosen words) python” (i’m a python guy and i want libraries handed to me and not mathimatical proof :P) Browser results and find an example with same looking hash on bottom of page 1.
This was a bit tricky since usually i would just google the hash and hope for google to make the connection to similar hashes on example, like it usually does. but on older challenges, I’ve found out that you cannot google any string found in the challenge without getting a straight answer / writeup. You could call it google-chi opposed to google-fu
