A command line tool to get information about JWT tokens
jwtinfo is a command line interface that allows you to inspect a given JWT token. The tool currently allows to see the body of the token in JSON format. It accepts a single command line argument which should be a valid JWT token.
Here's an example:
bash
jwtinfo eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c
Which will print:
json
{"sub":"1234567890","name":"John Doe","iat":1516239022}
You can combine the tool with other command line utilities, for instance jq:
bash
jwtinfo eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c | jq .
You can install the binary in your system with cargo:
bash
cargo install jwtinfo
At this point jwtinfo will be available as a binary in your system.
Note: pre-compiled binaries are not available at this stage.
