jsobf - The JSON Obfuscator

jsobf is an obfuscator for JSON documents that completely randomizes keys and values, but preserves the original structure (but not necessarily key order) of the JSON document and the original mapping of keys and values.

Why build jsobf? I wanted to obfuscate some sensitive JSON data but there was no simple CLI tool for it that I could trust.

Need a simple example? Let's obfuscate the following:

{
    "foo": "bar",
    "baz": {
        "test1": ["a", "b", "long string"],
        "test2" : false,
        "test3": 12
    },
    "qux": 13.37
}

becomes

{
  "0lH": {
    "84y8R": 7316513358385113447,
    "a9MEx": false,
    "jcML3": ["k", "n", "gIT6GsAhKEj"]
  },
  "0zv": 0.8398630941676407,
  "9Rf": "7qK"
}

Installation

cargo install jsobf

Usage

echo '{"foo": ["a", "b", "c"]}' | jsobf -

or

jsobf file.json
