       ## Reason

       21
       21
       +
       In my case the reason was to be able to easily prepare set of SSH keys for use

     

       22
       22
       +
       with [agenix][], tool for managing secrets while working with Nix deployments.

     

       23
       23
       +
       However usage can be extended to other situations as well:

     

       24
       24
       +
       

     

       25
       25
       +
       - Managing `allowed_signers` to check SSH signatures under commits and stuff

     

       26
       26
       +
       - Fetching `authorized_keys` to allow users to upload their keys without admin

     

       27
       27
       +
         manual intervention

     

       28
       28
       +
       

     

       29
       29
       +
       ## Usage

     

       30
       30
       +
       

     

       31
       31
       +
       Define configuration file, for example `keys.toml` in form:

     

       32
       32
       +
       

     

       33
       33
       +
       ```toml

     

       34
       34
       +
       [[entry]]

     

       35
       35
       +
       name = "hauleth"

     

       36
       36
       +
       emails = [ "~@hauleth.dev" ]

     

       37
       37
       +
       keys = [

     

       38
       38
       +
           { sourcehut = "~hauleth" },

     

       39
       39
       +
           { github = "hauleth" }

     

       40
       40
       +
       ]

     

       41
       41
       +
       

     

       42
       42
       +
       [[entry]]

     

       43
       43
       +
       name = "heimdall"

     

       44
       44
       +
       keys = [

     

       45
       45
       +
           { host = "heimdall" }

     

       46
       46
       +
       ]

     

       47
       47
       +
       ```

     

       48
       48
       +
       

     

       49
       49
       +
       Now you can run

     

       50
       50
       +
       

     

       51
       51
       +
       ```sh

     

       52
       52
       +
       fuk keys.toml > keys.json

     

       53
       53
       +
       ```

     

       54
       54
       +
       

     

       55
       55
       +
       And get JSON document containing all keys provided by these:

     

       56
       56
       +
       

     

       57
