The Crypt

The crypt is a program and library for storing encrypted text.

A crypt consists of three files that should be kept in separate locations for maximum security:

• Key file - stores a list of encryption keys
• IV file - stores a list of IVs
• Crypt file - stores a list of encrypted values

The theory (I'm no expert) is that without any one of these files, the data in the crypt file is useless, therefore secure.

Command line interface

The cli takes no arguments and after requesting the paths for the three files above, will act as a shell.

Usage

npx the-crypt

GUI

The GUI allows you to manage your crypt as easily as filling in an online form.

Usage

npx the-crypt ui

JavaScript API

The JavaScript API exposes the following function:

getCrypt({ keyFile: string, ivFile: string, cryptFile: string }): Object

This function returns an object with the following functions on it:

get(name: string): Buffer | undefined

This function returns the decrypted value associated with name or undefined.

set(name: string, value: string | Buffer): undefined

This function encrypts the value and writes the key, iv, and encrypted data to the appropriate files.

remove(name: string): undefined

This function removes the key, iv and encrypted data associated with name.

names(): string[]

This function returns a list of names stored in the crypt.
