Reference

NAME:
   jwtauth - Minimal cli to interact with JWT Auth Tokens

USAGE:
   jwtauth [global options] command [command options] [arguments...]

COMMANDS:
   claims, c         generate claims for a JWT token

   generate, g, gen  generate a new JWT token

Example

Create a hex encoded 256 bit jwt secret string (with a 0x prefix):

$ jwtauth g 0x66c01996d15563ec70b57ae35e22b739125094d40e5a6853746912b43ae56ce0

Generate the claims for the token that can be used in the Authorization header:

$ jwtauth c 0x66c01996d15563ec70b57ae35e22b739125094d40e5a6853746912b43ae56ce0

You can also set the token expiry in both the claims and header subcommands using the --expiry flag, providing a duration string. For example:

$ jwtauth c --expiry 100s 0x66c01996d15563ec70b57ae35e22b739125094d40e5a6853746912b43ae56ce0

The header subcommand simply prefixes Authorization: Bearer to the JWT Token like so.

$ jwtauth h --expiry 100s 0x66c01996d15563ec70b57ae35e22b739125094d40e5a6853746912b43ae56ce0
