I  know about computed-file, the issue is that the syntax of the key is
not strictly Scheme. The long hexadecimal block isn't parsed as a
number:
```
(with-input-from-file "/etc/guix/signing-key.pub" read)
...
/etc/guix/signing-key.pub:4:8: Unknown # object: #\C
```

Trying to store it as a module results in the same error.
So I can't just have an associative list of hostnames and signing keys
and filter it based on the hostname, I have to store each key as an
opaque file, completely bypassing the module system.
