\fB\-S\fR, \fB\-\-symmetric\fR <\fIfile\fR>
Use symmetric cryptography.
When doing "sign" or "verify" operation, do not sign asymmetrically, but
instead generate \fIfile\fR with cryptographic hashes that can later be used to
verify if the contents of input was changed.
Purpose of the \fB\-\-symmetric\fR option is that symmetric cryptography is a
lot faster than asymmetric, and symmetric primitives usually work also on very
large files and data streams. If working with a large file, process it
symetrically, then process the \fIfile\fR asymetrically and send it along with
the large file.
