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