Unimus currently only supports SSH keys without passwords, so the key being imported into Unimus must not be password-protected.
SSH private keys in the following formats are currently supported:
| rsa | dsa | ecdsa | ed25519 | |
|---|---|---|---|---|
| PEM | yes | yes | yes | no |
| PKCS8 | yes | yes | no | no |
| OpenSSH (RFC4716) | no | no | no | no |
Different versions of ssh-keygen (OpenSSH) use different default key types and formats across the different OpenSSH versions.
If you have an existing key in OpenSSH format, you can use ssh-keygen to transform key formats. This command will transform an OpenSSH private key into a PEM encoded key:
ssh-keygen -e -f /path/to/openssh.key -m PEM > /path/to/new_pem.key -e read OpenSSH formatted key -f read from file -m export format |
Alternatively, you can generate a new key pair already formatted in a supported format:
ssh-keygen -t ecdsa -m PEM -f /path/to/key -t use ecdsa type -m use PEM format -f output to file |
