Error loading key with ssh command

[arty-hlr]

Hi,

I am trying to make vault-cli ssh work, and unfortunately it does not want to load the private key:

vault-cli ssh --key kv/<REDACTED>:PRIV_KEY --passphrase kv/<REDACTED>:PASSPHRASE -- ssh <USER>@<IP>
Error: VaultSubprocessException: Error loading key "(stdin)": error in libcrypto
CalledProcessError: Command '['ssh-add', '-']' returned non-zero exit status 1.

whereas if I try to add the key manually, like https://github.com/peopledoc/vault-cli/blob/master/vault_cli/ssh.py#L48:

vault-cli get kv/<REDACTED> PRIV_KEY | ssh-add -
Enter passphrase for (stdin): <REDACTED_PASSPHRASE>
Identity added: (stdin) (<USER>@<IP>)

I am not sure what the issue could be as the private key is valid and correctly stored in vault with a kv1 engine.

Can you maybe have a look and see if you can reproduce it? :) Let me know if you need any more informations from my side.

Best
