Variables

View Source
var BcryptSecurityParameter = 12

BcryptSecurityParameter is security parameter var, and it can be changed within the lcd test. Making the bcrypt security parameter a var shouldn't be a security issue: One can't verify an invalid key by maliciously changing the bcrypt parameter during a runtime vulnerability. The main security threat this then exposes would be something that changes this during runtime before the user creates their key. This vulnerability must succeed to update this to that same value before every subsequent call to the keys command in future startups / or the attacker must get access to the filesystem. However, with a similar threat model (changing variables in runtime), one can cause the user to sign a different tx than what they see, which is a significantly cheaper attack then breaking a bcrypt hash. (Recall that the nonce still exists to break rainbow tables) For further notes on security parameter choice, see README.md
