It is not multiplication, it is permutation (170k!). I don't know how big this number is, however it is pretty big. This technic even has a name: diceware [1]

- m45t3r 8y agoSorry, not factorial either. More like 170k(170k - 1)(170k - 2). Generally I see people using Diceware with more than 3 words too (at least 4 or 5). However if the file does not need NSA levels of security 3 words seems fine.
- zeveb 8y ago> 170k(170k - 1)(170k - 2) Which is 4,912,913,300,340,000 ≈ 2^52. Fifty-two bits of entropy is pretty horrible for anything that you really care about: you want at least 128.
- AnaniasAnanas 8y agoIt's around 2^52 keys, which is pretty bad.
- AgentME 8y agoRight, a 52-bit key would be terrible for symmetric encryption. But that's not what Wormhole does. It uses PAKE, which is an interactive protocol that allows two parties that both know a short password to securely come up with a longer key for symmetric encryption.
