1026 Don't use this command in Lisp programs!
1027 Since this function operates on regions, it does some tricks such
1028 as coding-system detection and unibyte/multibyte conversion.  If
1029 you are sure how the data should be treated, you should consider
1030 using the string based counterpart `epg-encrypt-string', or the
1031 file based counterpart `epg-encrypt-file' instead.
