Storing keys and signatures as sexps

[Ludovic Courtès]

For the purposes of signing package binaries exported from Guix, I am
considering storing both key pairs and signatures using the sexp
‘advanced’ external representation [0].

AFAICS the format is generic, stable, and not libgcrypt-specific, so
this looks like a reasonable choice.

Nevertheless, is there anything you would caution about?

Thanks,
Ludo’.
