The size of the potential password space relies on the characters that are enabled (letters, numbers,
symbols, etc.) and the length of the password. Thus, the more complex and the longer passwords are used, the
larger the potential password space created is and the harder it is for adversaries to brute force an
otherwise unguessable password.
For example, the English dictionary with 26 letters (a-z), would create a password space of 26^P where P is
the length of the password. If we add case-sensitivity and numbers 0-9, this would change to 62^P.
(a-z,A-Z,0-9). Note, that unless passwords are randomly generated, dictionary-based attacks and password
guessing may simplify the attacks significantly, so password space alone is not a perfect measure of
