stash

stash is a command line program for storing text data in encrypted form.

All user data is encrypted using AES 256 cipher.

Data is hashed for indexing purposes using a good random salt + SHA512.

Rationale

All of us need to store sensitive information. At the very least, we need to keep passwords and keys to numerous online services we use. Storing them in plain-text is risky. So is not keeping backups in multiple locations.

stash is an open-source tool to store text in encrypted form. The encrypted data can be stored in untrusted locations without compromising it, granted the encryption-key is unguessable.

Installation

Linux and Mac

Install:

brew install rorokimdim/brew/stash

Upgrade:

brew upgrade stash

Uninstall:

brew uninstall stash

Binaries are available at releases.

Others

No pre-built binaries available at this time. We will need to build from source using stack install or cabal install.

Install stack, clone this repository and run the following in repository directory.

stack install

Getting Started

Create a stash file.

stash create {path-to-stash-file}

Replace {path-to-stash-file} with path to the stash file. For example ~/Dropbox/secret.stash.

Stash will prompt for the encryption-key (password) to use for the file. The key is not saved anywhere, but a salted hash (good random salt + SHA512) of the key and the salt is saved.

When we run a stash command, we will be prompted for our encryption key. It is checked against the hash stored during stash create. For the duration of the command, the encryption key will be used for encrypting/decrypting data.

The salt stored during stash create is also used for hashing any data for indexing purposes.

Browsing

This feature does not currently work on windows.

Terminal user interface (default)

stash browse {path-to-stash-file}

Shortcuts	Description
ESC (q)	Quit
?	Show this help
+	Add a new key
>	Add a child key to selected key
-	Delete selected key
, (r)	Rename selected key
/	Search and sort by pattern
y	Copy value of selected key into system clipboard
Enter	Set value of selected key
H	See history of values of selected key
Left arrow (h)	Move to parent of selected key

Down arrow (j, Ctrl-n)	Select below
g, G	Move to top, Move to bottom
Ctrl-u, Ctrl-d	Scroll keys half page up / down

As Org text

stash browse -f org {path-to-stash-file}

Opens as Org text in default editor. Set EDITOR environment variable to your editor command. Defaults to vim.

As Markdown text

stash browse -f markdown {path-to-stash-file}

Opens as markdown text in default editor. Set EDITOR environment variable to your editor command. Defaults to vim.

Dumping contents to stdout

As Org text (default)

stash dump -f org {path-to-stash-file}

As Markdown text

stash dump -f markdown {path-to-stash-file}

As JSON text

stash dump -f json {path-to-stash-file}

Backing up data

stash backup {path-to-stash-file}

Creates a timestamped copy of stash file in the same directory as the original file.

Importing text

We can import org and markdown text into stash. This feature is only available in version 0.2.0+.

cat {path-to-text-file} | stash import {path-to-stash-file}

stash import will assume text is in org format by default, but markdown is supported too:

cat {path-to-text-file} | stash import -f markdown {path-to-stash-file}

We can import from another stash file similarly:

stash dump {path-to-source-stash-file} | stash import {path-to-destination-stash-file}

We will need to first enter encryption-key for the source stash-file followed by encryption-key for the destination stash file.

Babashka pod support

stash exposes a bencode interface using Babashka Pod Protocol.

If you are familiar with clojure or babashka, see clojure-example.

Python folks see python-example.

Customization

A few things in stash can be customized via environment variables.

Name	Description	Possible Values	Default
`STASH_ENCRYPTION_KEY`	encryption key	-	prompt as needed
`STASH_WIPE_CLIPBOARD_AFTER_BROWSE`	wipe clipboard after browse	true, false	false
`STASH_LOG_LEVEL`	logging level	DEBUG, INFO, WARN, ERROR	INFO
`STASH_TUI_COLOR_SELECTED`	color of selected item	see below	cyan
`STASH_TUI_COLOR_CURRENT_PATH`	color of current path	see below	white
`STASH_TUI_COLOR_SORT_PATTERN`	color of sort/search text	see below	white
`BABASHKA_POD`	start as babashka-pod	true, false	false
`EDITOR`	command for editing text	-	vim

Color values can be one of black, red, green, yellow, blue, magenta, cyan, white, brightBlack, brightRed, brightGreen, brightYellow, brightBlue, brightMagenta, brightCyan and brightWhite.
