132 .TH RAND 1 "2009-06-14" "0.9.8k" "OpenSSL"
134 rand \- generate pseudo\-random bytes
136 .IX Header "SYNOPSIS"
138 [\fB\-out\fR \fIfile\fR]
139 [\fB\-rand\fR \fIfile(s)\fR]
144 .IX Header "DESCRIPTION"
145 The \fBrand\fR command outputs \fInum\fR pseudo-random bytes after seeding
146 the random number generator once. As in other \fBopenssl\fR command
147 line tools, \s-1PRNG\s0 seeding uses the file \fI$HOME/\fR\fB.rnd\fR or \fB.rnd\fR
148 in addition to the files given in the \fB\-rand\fR option. A new
149 \&\fI$HOME\fR/\fB.rnd\fR or \fB.rnd\fR file will be written back if enough
150 seeding was obtained from these sources.
153 .IP "\fB\-out\fR \fIfile\fR" 4
155 Write to \fIfile\fR instead of standard output.
156 .IP "\fB\-rand\fR \fIfile(s)\fR" 4
157 .IX Item "-rand file(s)"
158 Use specified file or files or \s-1EGD\s0 socket (see \fIRAND_egd\fR\|(3))
159 for seeding the random number generator.
160 Multiple files can be specified separated by a OS-dependent character.
161 The separator is \fB;\fR for MS\-Windows, \fB,\fR for OpenVMS, and \fB:\fR for
163 .IP "\fB\-base64\fR" 4
165 Perform base64 encoding on the output.
168 Show the output as a hex string.
