## Add existing keys or convert format to RFC
|
|
|
|
|
|
|
|
|
|
**Use both mechanisms (RFC and standard) for maximum compatibility.**
|
|
|
|
|
|
|
|
|
|
Example how `.ssh/authorized_keys` might look:
|
|
|
|
|
|
|
|
|
|
```shell
|
|
|
|
|
ssh-rsa AA.... user@host
|
|
|
|
|
---- BEGIN SSH2 PUBLIC KEY ----
|
|
|
|
|
Comment: "2048-bit RSA, converted by user@host from OpenSSH"
|
|
|
|
|
AA.....
|
|
|
|
|
---- END SSH2 PUBLIC KEY ----
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
**Use https://docs.hetzner.com/robot/storage-box/backup-space-ssh-keys#converting-your-key-to-rfc4716-format!**
