Hi,  
I cannot clone repository because of  
`Failed (SshException) to authenticate using factory method=publickey: key spec not recognised: class net.i2p.crypto.eddsa.spec.EdDSAPublicKeySpec`  
I use this ed21559 key with github and other ssh connections and its working.  
Using SCM-Manager on Debian 12 with default-jre. Is something missing?  
Are Ed25519 key not supported?  
Kind regards
