objfuscate v0.2.0
Objfuscate
Redacts JSON object values recursively, and keys if desired.
Installation
npm install -g objfuscate
Usage
Usage:
objfuscate [options] <jsonfile>
objfuscate --version
objfuscate -h | --help
Options:
-h, --help Print this help screen
-k, --include-keys Obfuscate keys as well
-p, --pretty Print the result with line breaks and indentation
Use with a JSON file
objfuscate ./sensitive.json
This will write the obfuscated JSON to stdout. In most cases, you will want to store the result in another file, which you can do like so:
objfuscate ./sensitive.json > obfuscated.json
Note: The file can be a single JSON object, a newline-delimited list of JSON objects (for example when using mongoexport
without the --jsonArray
option) or an array of JSON objects (for example when using mongoexport
with the --jsonArray
option). The output format matches the input format.
Use with JSON string
objfuscate '{"my": "secret"}'
Note: The JSON string must be wrapped in single quotes and you need to write proper JSON, which includes double quotes around key names and strings.
Value Obfuscation
Currently, only the following values are replaced:
- Strings
- Numbers
Values use a cache so that each value is replaced with the same random value, which is created when a particular value is first encountered. This ensures that the dataset has the same cardinality as the original.
Key Obfuscation
To replace object keys as well, use the -k
or --include-keys
option like so:
objfuscate -k ./paranoid.json
objfuscate --include-keys ./paranoid.json
They key cache is the same as the value cache (see above). A key named "foo"
is replaced with the same new string as the value "foo"
.
Pretty output
(Only applicable if the input file was a single JSON object, or an array of JSON objects. Newline-delimited JSON objects are not prettified.)
Per default, the output is written compressed into a single line without whitespace. If you want the output to be nicely formatted with line breaks, whitespace and indentations, use the -p
or --pretty
option.
objfuscate --pretty ./documents.json > pretty-obfuscated.json
