epg-start-delete-keys is a compiled Lisp function in `epg.el
'.
(epg-start-delete-keys CONTEXT KEYS &optional ALLOW-SECRET)

If you use this function, you will need to wait for the completion of
`epg-gpg-program' by using `epg-wait-for-completion' and call
`epg-reset' to clear a temporary output file.
If you are unsure, use synchronous version of this function
`epg-delete-keys' instead.
