(2024.04.02 and earlier) Private key for accessing the bastion host is invalid

When a user downloads the private key for accessing the bastion host from the RES web portal, the key is not well formatted: Multiple lines are downloaded as a single line, which makes the key invalid. The user will get the following error when attempting to access the bastion host with the downloaded key:

Load key "<downloaded-ssh-key-path>": error in libcrypto
<user-name>@<bastion-host-public-ip>: Permission denied (publickey,gssapi-keyex,gssapi-with-mic)

We recommend using Chrome to download the keys as this browser is unaffected.

Alternatively, the key file can be reformatted by creating a new line after -----BEGIN PRIVATE KEY----- and another new line just before -----END PRIVATE KEY-----.
