JSONe

jsone is a ejson clone but written in Ruby. Utility encrypts strings in JSON files using public key cryptography (thanks to rbnacl's SimpleBox).

Installation

gem install jsone

Usage

1: Create keys directory

By default, looks for keys in /opt/jsone/keys. You can change this by setting JSONE_KEYDIR

$ mkdir -p /etc/jsone/keys

2: Generate a key pair

$ jsone keygen
Key pair has been saved to /etc/jsone/keys/d586f99465b6f1dc7ff37c604e8e875eafbcf7770206fbb14473f3792065613c

   JSONE_KEY=d586f99465b6f1dc7ff37c604e8e875eafbcf7770206fbb14473f3792065613c
   export JSONE_KEY

to your environment for convenience.

With --env option JSONE_KEY will be added to .env file if it exists

3: Encrypting

$ cat config.json
{
  "api_key": "123qwerty",
  "password": "123143",
  "foo": "bar"
}
$ export JSONE_KEY=d586f99465b6f1dc7ff37c604e8e875eafbcf7770206fbb14473f3792065613c
$ jsone encrypt config.json -v 
* encrypting config.json with d586f99465b6f1dc7ff37c604e8e875eafbcf7770206fbb14473f3792065613c

Encrypted files are saved with .jsone extension:

$ cat config.jsone
{
  "__jsone_public_key": "d586f99465b6f1dc7ff37c604e8e875eafbcf7770206fbb14473f3792065613c",
  "api_key": "__!jsone__J5zMgvtZ93uUr6bkkfZ8pKXyqkhSfWRdokyg34fHCrYbY5ec6t3VPN+fCgld\ndGsY6w==\n",
  "password": "__!jsone__13E6u2fpA1Z3snWPQo1f2NDZhtcVHoAOrc4U19bG+UCNQ1cKki7aDP9VkSs9\nSg==\n",
  "foo": "__!jsone__eisgcjhKityeO1ykA59L7/R6Sd5USSV7XChHWqHf1eIiAjAjffL5AoaBoQ==\n"
}

4: Decrypting

With decrypt command file will be decrypted and saved back as .json

$ json decrypt config.jsone -v
* decrypting config.jsone
$ cat config.jsone
{
  "__jsone_public_key": "d586f99465b6f1dc7ff37c604e8e875eafbcf7770206fbb14473f3792065613c",
  "api_key": "123qwerty",
  "password": "123143",
  "foo": "bar"
}

Notes

• jsone encrypt DIR and jsone decrypt DIR will recursively encrypts/decrypts all JSON(e) files in DIR
• with --stdout encryption/decrption results will be printed to stdout
• jsone load PWD/.env file at start (using dotenv)
