...use an ordered list of the most likely passwords. They start with "password123" and progress to less frequently used passwords.
Let's say an attackers list is long, with 10 billion candidates; suppose also that a desktop system can compute 1 million hashes per second. The attacker can test her who...
Flatten nested dictionaries, compressing keys

Test:
In [2]: flatten_dict({'abc':123, 'hgf':{'gh':432, 'yu':433}, 'gfd':902, 'xzxzxz':{"432":{'0b0b0b':231}, "43234":1321}}, '.')
Out[2]:

'gfd': 902,
'hgf.gh': 432,
'hgf.yu': 433,

reflect.ValueOf(&foo).Elem().Field(0).SetInt(321)
fmt.Println(int(reflect.ValueOf(foo).Field(0).Int()))
}
Prints:
123
