 # sj (Swagger Jacker)

 sj is a command line tool designed to assist with auditing of exposed Swagger/OpenAPI definition files by checking the associated API endpoints for weak authentication. It also provides command templates for manual vulnerability testing.

+It does this by parsing the definition file for paths, parameters, and accepted methods before using the results with one of four commands:
 - `automate` - Crafts a series of requests and analyzes the status code of the response.

+```bash
+$ sj --help
+The process of reviewing and testing exposed API definition files is often tedious and requires a large investment of time for a thorough review.
+
+sj (swaggerjacker) is a CLI tool that can be used to perform an initial check of API endpoints identified through exposed Swagger/OpenAPI definition files. 
+Once you determine what endpoints require authentication and which do not, you can use the "prepare" command to generate command templates for further (manual) testing.
+
+Example usage:
+
+Perform a quick check of endpoints which require authentication:
+$ sj automate -u https://petstore.swagger.io/v2/swagger.json
+
+Generate a list of commands to use for manual testing:
+$ sj prepare -u https://petstore.swagger.io/v2/swagger.json
+
+Generate a list of raw API routes for use with custom scripts:
+$ sj endpoints -u https://petstore.swagger.io/v2/swagger.json
+
+Perform a brute-force attack against the target to identify hidden definition files:
+$ sj brute -u https://petstore.swagger.io
+
+Usage:
+  sj [flags]
+  sj [command]
+
+Available Commands:
+  automate    Sends a series of automated requests to the discovered endpoints.
+  brute       Sends a series of automated requests to discover hidden API operation definitions.
+  endpoints   Prints a list of endpoints from the target.
+  help        Help about any command
+  prepare     Prepares a set of commands for manual testing of each endpoint.
+
+Flags:
+  -a, --agent string            Set the User-Agent string. (default "Swagger Jacker (github.com/BishopFox/sj)")
+  -b, --base-path string        Set the API base path if not defined in the definition file (i.e. /V2/).
+  -f, --format string           Declare the format of the definition file (json/yaml/yml/js). (default "json")
+  -H, --headers stringArray     Add custom headers, separated by a colon ("Name: Value"). Multiple flags are accepted.
+  -h, --help                    help for sj
+  -i, --insecure                Ignores server certificate validation.
+  -l, --local-file string       Loads the documentation from a local file.
+  -o, --outfile string          Output the results to a file. Only supported for the 'automate' and 'brute' commands at this time.
+  -p, --proxy string            Proxy host and port. Example: http://127.0.0.1:8080 (default "NOPROXY")
+  -q, --quiet                   Do not prompt for user input - uses default values for all requests.
+  -r, --randomize-user-agent    Randomizes the user agent string. Default is 'false'.
+  -s, --safe-word stringArray   Avoids 'dangerous word' check for the specified word(s). Multiple flags are accepted.
+  -T, --target string           Manually set a target for the requests to be made if separate from the host the documentation resides on.
+  -t, --timeout int             Set the request timeout period. (default 30)
+  -u, --url string              Loads the documentation file from a URL
+  -v, --version                 version for sj
+
+Use "sj [command] --help" for more information about a command.
