epg-start-verify
epg-start-verify is a compiled Lisp function in `epg.el
'.
(epg-start-verify CONTEXT SIGNATURE &optional SIGNED-TEXT)
Initiate a verify operation on SIGNATURE.
SIGNATURE and SIGNED-TEXT are a data object if they are specified.
For a detached signature, both SIGNATURE and SIGNED-TEXT should be set.
For a normal or a cleartext signature, SIGNED-TEXT should be nil.
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-verify-file' or `epg-verify-string' instead.
