推荐答案

首先，它没有被记录为线程安全的，因此就所有意图和目的而言，它不是.而且，在进一步调查中，绝对不是:事实证明，虽然有一些实例字段，但没有暴露的 BCrypt 实例；它试图通过静态方法完成所有事情.它可能不是线程安全的.它足够小，假设您关心并且作者会接受，您可以提供一个补丁来简单地将其转换为提供单独的安全实例(编辑添加:我已经仔细擦洗并准备了一个更干净的版本，我将发送给作者...)

First, it's not documented as thread-safe, so for all intents and purposes, it's not. And, on further investigation, it's definitely not: It turns out that, while there are some instance fields, there is no instance of BCrypt exposed; it tries to do everything through static methods. It may not be thread safe. It's small enough that, assuming you care and the author would accept, you could offer a patch to trivially convert it to provide separate, safe instances (edit to add: I have scrubbed it carefully and prepared a cleaner version, which I will send to the author...)

第二，你想在多线程环境中以什么方式使用它?我不清楚你想在不同的线程中做什么.

Second, in what manner do you want to use this in a multithreaded environment? It's not clear to me what you'd want to do in separate threads.
