resign-jwt

A tool for re-signing jwts. For example, you may have a development environment that needs a JWT, but does not have the ability to create them. This tool allows you to re-sign a jwt from another environment with the secret for your development environment.

Install

cargo install -f resign-jwt

Usage

You can see usage at any time with --help

resign-jwt --help

Typically you'll want to provide three things

• the old --jwt (-j) (note: you only need to provide the first two parts if you have security concerns)
• the --algorithm (-a) to use (currently only HSxxx algorithms below, see issues)
• the new --key (-k) to use for signing
