MD5 hash , basic question

[qaksmmnvkpjv]

In that case you could write a bash or a python script to iterate over the 1,000,000 possibilities.

Something like:
password = None
for i in range(1000000):
    guess = str(i).zfill(6).encode("utf-8")
    for j in range(10000):
        guess = md5(guess)
    if guess == hash:
        password = guess
        break
print(password)
