EMQX JWT Authentication Plugin

Build

make && make tests

Configure the Plugin

File: etc/plugins/emqx_auth_jwt.conf

## HMAC Hash Secret.
##
## Value: String
auth.jwt.secret = emqxsecret

## From where the JWT string can be got
##
## Value: username | password
## Default: password
auth.jwt.from = password

## RSA or ECDSA public key file.
##
## Value: File
## auth.jwt.pubkey = etc/certs/jwt_public_key.pem

## Enable to verify claims fields
##
## Value: on | off
auth.jwt.verify_claims = off

## The checklist of claims to validate
##
## Value: String
## auth.jwt.verify_claims.$name = expected
##
## Variables:
##  - %u: username
##  - %c: clientid
# auth.jwt.verify_claims.username = %u

Load the Plugin

./bin/emqx_ctl plugins load emqx_auth_jwt

Example

mosquitto_pub -t 'pub' -m 'hello' -i test -u test -P eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJuYW1lIjoiYm9iIiwiYWdlIjoyOX0.bIV_ZQ8D5nQi0LT8AVkpM4Pd6wmlbpR9S8nOLJAsA8o

Algorithms

The JWT spec supports several algorithms for cryptographic signing. This plugin currently supports:

  • HS256 - HMAC using SHA-256 hash algorithm

  • HS384 - HMAC using SHA-384 hash algorithm

  • HS512 - HMAC using SHA-512 hash algorithm

  • RS256 - RSA with the SHA-256 hash algorithm

  • RS384 - RSA with the SHA-384 hash algorithm

  • RS512 - RSA with the SHA-512 hash algorithm

  • ES256 - ECDSA using the P-256 curve

  • ES384 - ECDSA using the P-384 curve

  • ES512 - ECDSA using the P-512 curve
