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