## Using age encryption
{: .note }
Even though the `age` CLI tools supports encryption using SSH keys, this is not supported by this tool.
`AGE_PUBLIC_KEYS` currently expects `age` keys to be given.
age allows backups to be encrypted with either a symmetric key (password) or a public key. One of those options are available for use.
Given `AGE_PASSPHRASE` being provided, the backup archive will be encrypted with the passphrase and saved as a `.age` file instead. Refer to age documentation for how to properly decrypt.
