top | item 29963971 (no title) spacehome | 4 years ago Individual passwords don’t have entropy. discuss order hn newest MattPalmer1086|4 years ago You can calculate Shannon entropy of an individual password, as the number of bits per char.A password of "aaaaaaa" will have a much lower entropy than "axipeY7".What am I missing? MattPalmer1086|4 years ago Replying to self...I guess it's not a useful measure of password strength, even if possible. Any password that doesn't repeat any letters will have identical entropy by this measure.So 123456789 will be the same Shannon entropy as Ar4e$hUa^ load replies (1)
