Master key bruteforce attackSafe 256-bit master key derived from wallet is impossible to bruteforceAt Risk Humans can create weak master keys
Encryption Algorithm ObsolescenceSafe Passwords not stored, thus not affectedAt Risk Stored passwords may become vulnerable
Master Key Recovery Mechanism ExploitedSafe Master key derived from wallet onlyAt Risk Recovery mechanisms can be a weak point
