Lockedbox

Lockedbox is a small tool to make it very difficult to access a secret (e.g. Steam or Netflix password), except at a given time of day or week.

This can be useful if you need a little help in being disciplined around usage of certain services (e.g. gaming, entertainment, etc).

Installation and pre-requisites

If you wish to build lockedbox for yourself, you need golang; https://golang.org/doc/install.

How to build

NOTE: The program has the blocked/unblocked times hard-coded into it. You must change these in the lockedbox.go file first before building.

NOTE: The key used to encrypt/decrypt your secrets is generated mathematically by a formula on line 66. Tweak these values slightly after building to ensure you cannot modify the program after encryption to easily decrypt your secrets.

Open lockedbox.go
Go to line 46 ("Decryption only allowed at certain times")
Adjust the logic to suit your needs (e.g. I want it allowed every day after 8PM)
Run build in terminal:

go build

Adjust values on line 66 slightly, save file

This should create an executable suitable for usage on your system.

How to use

lockedbox [encrypt|decrypt] [secret|cypher]

Encrypting

lockedbox encrypt MySteamPassword

This will encrypt your secret.

WARNING: Please do not lose your encrypted secret.

WARNING: Please test decryption and give a backup to a family member or friend before deleting your unecrypted copy of the secret

Decrypting

On the configured days and hours, you will be able to decrypt your secret:

lockedbox decrypt 3423-fsdf3-sdfaerASDGjhasgdhjsdagsda
