Options

  -h, --help                  Display this help
  -d, --decode                Decode an encoded jwt token
  -e, --encode                Encode a decoded jwt token - requires secret or private key
  -s, --secret string         Used with decode and encode - when used with decode the jwt token is verified

HS256 Examples

Decode a HS256 token

jwt --decode eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiYWRtaW4iOnRydWV9.TJVA95OrM7E2cBab30RMHrHDcEfxjoYZgeFONFh7HgQ
{"sub":"1234567890","name":"John Doe","admin":true}

Encode a HS256 token using secret

jwt --encode --secret secret '{"sub":"1234567890","name":"John Doe","admin":true}'

Development

Check jwt is not installed globally:

$ which jwt
jwt not found

Maybe uninstall it:

npm --global uninstall jsonwebtokencli

In the project directory, use npm link:

$ npm link
/usr/local/bin/jwt -> /usr/local/lib/node_modules/jsonwebtokencli/main.js

Check it worked:

$ which jwt
/usr/local/bin/jwt

Unlink when finished:

$ npm unlink

Known Issues

  • There is little to no validation performed, so error messages leave a lot to be desired.
