A quick way to run a single file through a bunch of hashing algorithms, via Python's hashlib

python-hashing.py

import hashlib
filename = '/home/vanessa/.singularity/shub/vanessa-marshmallow-latest@8dc77d81e1775986b89f042112c5ee81.sif'
for algorithm in hashlib.algorithms_guaranteed:
    hasher = getattr(hashlib, algorithm)()
    with open(filename, "rb") as f:
        for chunk in iter(lambda: f.read(4096), b""):
            hasher.update(chunk)
    try:
        print("%s: %s" %(algorithm, hasher.hexdigest()))
    except:
        pass
