使用OpenSSL生成素数 [英] Generate prime number using OpenSSL
问题描述
我如何使用openssl生成一个大的随机素数,我发现了如何生成一个随机数并检查它是否为素数,但是我无法自动化检查素数的过程,这是我的命令正在使用:openssl rand -hex 256 | xargs openssl prime -hex
How can I generate a large random prime using openssl, I found out how to generate a random number and check if it is prime but I have not been able to automate the process of checking the primality, here is the command that i am using: openssl rand -hex 256 | xargs openssl prime -hex
是否应该使用 while循环重复检查结果是否为质数?如何自动检查结果是否不包含关键字"not",
Should I use a while loop to repeatedly check if the result is prime? How can I automate the process of checking if the result does not contain the keyword "not",
这是我编写while循环的全部内容:
This is all the further i got on writing the while loop:
while [{openssl rand -hex 256 | xargs openssl prime -hex} = *"$not"*]
推荐答案
OpenSSL版本1.0.0及更高版本将-generate
选项添加到prime
命令:
OpenSSL version 1.0.0 and newer adds -generate
option to the prime
command:
$ openssl prime -generate -bits 2048 -hex
