=head1 NAME
|
||
|
||
rand - generate pseudo-random bytes
|
||
|
||
=head1 SYNOPSIS
|
||
|
||
B<gmssl rand>
|
||
[B<-help>]
|
||
[B<-out> I<file>]
|
||
[B<-rand> I<file(s)>]
|
||
[B<-base64>]
|
||
[B<-hex>]
|
||
I<num>
|
||
|
||
=head1 DESCRIPTION
|
||
|
||
The B<rand> command outputs I<num> pseudo-random bytes after seeding
|
||
the random number generator once. As in other B<gmssl> command
|
||
line tools, PRNG seeding uses the file I<$HOME/>B<.rnd> or B<.rnd>
|
||
in addition to the files given in the B<-rand> option. A new
|
||
I<$HOME>/B<.rnd> or B<.rnd> file will be written back if enough
|
||
seeding was obtained from these sources.
|
||
|
||
rand命令在播放随机数生成器一次后输出num伪随机字节。 与其他gmssl命令行工具一样，
|
||
除了-rand选项中提供的文件外，PRNG种子使用文件$ HOME / .rnd或.rnd。
|
||
如果从这些来源获得足够的播种，将会写入新的$ HOME / .rnd或.rnd文件。

|
||
|
||
=over 4
|
||
|
||
=item B<-help>
|
||
|
||
Print out a usage message.
|
||
|
||
输出使用信息
|
||
|
||
=item B<-out> I<file>
|
||
|
||
Write to I<file> instead of standard output.
|
||
|
||
写入file而不是标准输出。
|
||
|
||
=item B<-rand> I<file(s)>
|
||
|
||
Use specified file or files or EGD socket (see L<RAND_egd(3)>)
|
||
for seeding the random number generator.
|
||
Multiple files can be specified separated by an OS-dependent character.
|
||
The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for
|
||
all others.
|
||
|
||
使用指定的文件或EGD套接字（请参阅RAND_egd（3））播放随机数生成器。
|
||
多个文件可以由与操作系统相关的字符分隔。 分离器是 对于MS-Windows，对于OpenVMS
|
||
，以及：对于所有其他。
|
||
|
||
=item B<-base64>
|
||
|
||
Perform base64 encoding on the output.
|
||
|
||
在输出上执行base64编码。
|
||
|
||
=item B<-hex>
|
||
|
||
Show the output as a hex string.
|
||
|
||
将输出显示为十六进制字符串。
