155 .IX Header "DESCRIPTION"
156 The \fBrand\fR command outputs \fInum\fR pseudo-random bytes after seeding
157 the random number generator once. As in other \fBopenssl\fR command
158 line tools, \s-1PRNG\s0 seeding uses the file \fI\f(CI$HOME\fI/\fR\fB.rnd\fR or \fB.rnd\fR
159 in addition to the files given in the \fB\-rand\fR option. A new
160 \&\fI\f(CI$HOME\fI\fR/\fB.rnd\fR or \fB.rnd\fR file will be written back if enough
161 seeding was obtained from these sources.
164 .IP "\fB\-out\fR \fIfile\fR" 4
166 Write to \fIfile\fR instead of standard output.
167 .IP "\fB\-rand\fR \fIfile(s)\fR" 4
168 .IX Item "-rand file(s)"
169 Use specified file or files or \s-1EGD\s0 socket (see \fIRAND_egd\fR\|(3))
170 for seeding the random number generator.
171 Multiple files can be specified separated by a OS-dependent character.
172 The separator is \fB;\fR for MS-Windows, \fB,\fR for OpenVMS, and \fB:\fR for
174 .IP "\fB\-base64\fR" 4
176 Perform base64 encoding on the output.
179 Show the output as a hex string.
