Github Publickey denied

[Chandler B. (chandler)]

Hallo,
ich habe ein Problem mit Github.
Ich habe einen PC mit Windows und Git.
mittels der Git-Bash habe ich mir einen RSA-Key generiert und diesen in 
Github hochgeladen.

ssh-rsa AAAAB3NzaC1y..........

wenn ich jetzt das Projekt clonen möchte, bekomme ich den Fehler

[e-mail]: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

in der Datei ~/.ssh/known_hosts steht auch nur ein key

github.com ssh-ed25519 AAAAC3NzaC1.......

auch wenn ich diese datei lösche und neu erstelle, steht nur derselbe 
key drinn.
In Github selber, steht aber nur mein RSA-Key.

was kann/habe ich falsch gemacht?

Versuch ein
> ssh -v [e-mail]

Und schau dir in der Log-Ausgabe an, ob der auch den Secret-Key zu dem 
Public-Key, den du bei github hinterlegt hast, einliest.

was ich hier sehen kann, ist dass id_rsa eingelesen wird? Die keys 
heißen aber github und github.pub

kann das das problem sein?

Ja, das war das problem.
jetzt heißen die Dateien id_rsa und id_rsa.pub.
Damit funktioniert jetzt alles :/

Den Dateinamen des für den jeweiligen Host zu verwendenen Keyfiles kann 
man auch selbst aktiv setzen via "~/.ssh/config"-Datei:
