### Question:
RecoveryKeyFactory { public boolean validateRecoveryKey(String recoveryKey) { try { byte[] key = decodeRecoveryKey(recoveryKey); Arrays.fill(key, (byte) 0x00); return true; } catch (IllegalArgumentException e) { return false; } } @Inject  RecoveryKeyFactory(WordEncoder wordEncoder); Collection<String> getDictionary(); String createRecoveryKey(Path vaultPath, CharSequence password); void resetPasswordWithRecoveryKey(Path vaultPath, String recoveryKey, CharSequence newPassword); boolean validateRecoveryKey(String recoveryKey);  }### Answer:
