sa-jwt-claims-validate
======================

Plugin functionality:

supposed to work in combination with kong's built-in jwt plugin.
Built-in plugin is responsible for validation of the jwt token signature and validity/expiration claims.

This plugin - exposes plugin claims to upstream services via headers,
additionally it can be used as a security filter to enforce presence of
specified claims and checking they are matching expected values.

## (A) expose jwt token info to upstream services

For incoming token (location configurable)
```

which is equivalent of jwt token

header
```
{
"typ": "JWT",
"alg": "RS256",
"kid": "QzlFNjNBRkY5RjcyNUZBRjI1NjFBN0YxOEM1REIxMzU4MUIyNjkwRQ"
}
```

payload
```
{
"iss": "https://voronenko.auth0.com/",
"sub": "R477zd0dhD0Hq3CnNIEgE677nwboYD5u@clients",
"aud": "https://implicitgrant.auth0.voronenko.net",

"azp": "R477zd0dhD0Hq3CnNIEgE677nwboYD5u",
"gty": "client-credentials"
}
```

it will expose following headers to upstream service:

```
"x-sa-jwt-claim-gty":"client-credentials",
"x-sa-jwt-claim-exp":"1575669936",
"x-sa-jwt-claim-azp":"R477zd0dhD0Hq3CnNIEgE677nwboYD5u"
