# Convert a public Ed25519 key (in PEM format) for use in ClusterCockpit
|
||
|
|
|
||
|
|
Imagine you have externally generated JSON Web Tokens (JWT) that should be accepted by CC backend. This external provider shares its public key (used for JWT signing) in PEM format:
|
||
|
|
|
||
|
|
```
|
||
|
|
-----BEGIN PUBLIC KEY-----
|
||
|
|
MCowBQYDK2VwAyEA+51iXX8BdLFocrppRxIw52xCOf8xFSH/eNilN5IHVGc=
|
||
|
|
-----END PUBLIC KEY-----
|
||
|
|
```
|
||
|
|
|
||
|
|
Unfortunately, ClusterCockpit does not handle this format (yet). You can use this tool to convert the public PEM key into a representation for CC:
|
||
|
|
|
||
|
|
```
|
||
|
|
CROSS_LOGIN_JWT_PUBLIC_KEY="+51iXX8BdLFocrppRxIw52xCOf8xFSH/eNilN5IHVGc="
|
||
|
|
```
|
||
|
|
|
||
|
|
Instructions
|
||
|
|
|
||
|
|
- `cd tools/convert-pem-pubkey-for-cc/`
|
||
|
|
- Insert your public ed25519 PEM key into `dummy.pub`
|
||
|
|
- `go run . dummy.pub`
|
||
|
|
- Copy the result into ClusterCockpit's `.env`
|
||
|
|
- (Re)start ClusterCockpit backend
|
||
|
|
|
||
|
|
Now CC can validate generated JWTs from the external provider.
