rand - generate pseudo-random bytes
gmssl rand [-help] [-out file] [-rand file(s)] [-base64] [-hex] num
The rand command outputs num pseudo-random bytes after seeding the random number generator once. As in other gmssl command line tools, PRNG seeding uses the file $HOME/.rnd or .rnd in addition to the files given in the -rand option. A new $HOME/.rnd or .rnd file will be written back if enough seeding was obtained from these sources.
rand命令在播放随机数生成器一次后输出num伪随机字节。 与其他gmssl命令行工具一样， 除了-rand选项中提供的文件外，PRNG种子使用文件$ 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。
