# jwtgen
Command line tool that generates JWT tokens that helps in the testing of applications.
## Features
* Signatures for HMAC-SHA256, HMAC-SHA384, HMAC-SHA512 and RSA-SHA256
* Issued at (iat) and expiry (exp) values can be configured as offsets
* Claims can be encoded as JSON or as separate arguments
## Installation
Install via npm.
npm install -g jwtgen
## Getting Started
The following command will generate a JWT using HMAC-SHA256, a shared secret of `my-secret`, expires in 1 hour and contains user id of `user123` as the `iss` value.
```
jwtgen -a HS256 -s "my-secret" -c "iss=user123" -e 3600
eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJ1c2VyMTIzNCIsImlhdCI6MTQ
1NzU1NTQwNSwiZXhwIjoxNDU3NTU5MDA1fQ.nixEkSKDkru92TBsxdzR8GLANIGQrkRa7E21
C-luNg
```
If the same command is run with the `-v` option, a more verbose output is displayed.
```
jwtgen -a HS256 -s "my-secret" -c "iss=user123" -e 3600 -v
algorithm: HS256
claims:
{
"iss": "user1234",
"iat": 1457555405,
"exp": 1457559005
}
token:
eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJ1c2VyMTIzNCIsImlhdCI6MTQ
1NzU1NTQwNSwiZXhwIjoxNDU3NTU5MDA1fQ.nixEkSKDkru92TBsxdzR8GLANIGQrkRa7E21
C-luNg
```
## Expired Tokens
Expired tokens can be generated by specifying an offset to the `iat` value. The following example issues the token 1 hour (3600 seconds) in the past and expires at the generated time.
```
jwtgen -a HS256 -s "my-secret" -c "iss=user1234" -i=-3600 -e 3600 -v
algorithm: HS256
claims:
{
"iss": "user1234",
"iat": 1457552128,
"exp": 1457555728
}
token:
eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJ1c2VyMTIzNCIsImlhdCI6MTQ
1NzU1MjEyOCwiZXhwIjoxNDU3NTU1NzI4fQ.1SoNk-bCy8l3stfN8q4yrjBjbQkaRWP8AMyP
joDDeHE
```
## Tokens Not Valid Yet
Tokens that are not yet valid can be generated by specifying the `iat` value directly as in the following example:
```
jwtgen -a HS256 -s "my-secret" -c "iss=user1234" -i=1557555728 -e 3600 -v
algorithm: HS256
claims:
{
"iss": "user1234",
"iat": 1557555728,
"exp": 1557559328
}
token:
eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJ1c2VyMTIzNCIsImlhdCI6MTU
