epg-start-edit-key is a compiled Lisp function in `epg.el'.

(epg-start-edit-key CONTEXT KEY EDIT-CALLBACK HANDBACK)

Initiate an edit operation on KEY.

EDIT-CALLBACK is called from process filter and takes 3
arguments: the context, a status, an argument string, and the
handback argument.

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-edit-key' instead.
