如何使OpenSSL在Windows Vista上写入RANDFILE? [英] How do I make OpenSSL write the RANDFILE on Windows Vista?

问题描述

当我跑步时:

openssl genrsa -out mykey.key 2048

我收到以下错误:

unable to write 'random state'
    e is 65537 (0x10001)

我的Google搜索表明这是某种Vista权限问题.如何允许Vista写入此文件，或者如何配置openssl来解决这个问题?

My googling suggests this is some kind of Vista permissions issue. How can I allow Vista to write this file or how can I configure openssl to get round it?

推荐答案

根本问题是OpenSSL配置文件中的RANDFILE变量在Windows上被忽略.这是一个长期存在的问题，并一直持续到从OpenSSL v1.0a版本开始存在，而不论目标Windows平台是x86还是x64.

The root issue is that the RANDFILE variable in the OpenSSL configuration file is ignored on Windows. This has been a long-standing problem that continues to exist as of the OpenSSL v1.0a release, regardless of whether the target Windows platform is x86 or x64.

不过，有一个非常简单的解决方案.只需使用常规环境变量来设置RANDFILE值，例如

There is a delightfully simple solution, though. Merely use a regular environmental var to set the RANDFILE value, like

set RANDFILE=.rnd

由于此值是临时值，因此必须为每个新的DOS框重新发出该值，或在批处理文件中编写该脚本.

Because this value is ephemeral, it must be re-issued for every new DOS box, or scripted in a batch file.
