jruby bundle 安装在 gem 'scrypt' 时不工作

Question

我正在尝试为 jruby (Windows) 执行捆绑安装，但出现此错误：

我已经安装了 jruby 和 JVM。

您正在尝试在 java 版本的 ruby 中安装带有本机扩展的 gem：通常是个坏主意...

我在 https://github.com/wg/scrypt 找到了纯 java scrypt 算法的实现。

您需要从 Maven (http://search.maven.org/remotecontent?filepath=com/lambdaworks/scrypt/1.4.0/scrypt-1.4.0.jar) 下载 jar 文件，将其添加到您的库路径或在您的代码中 require jar。

下一步是编写一个包装器来模仿 scrypt 行为，将其用作 ruby/rails 代码中的直接替换。

或者，您可以只删除 scrypt 位并直接使用 java 库。这是在 jirb (1.7.20) 中测试的片段...

>> require 'java'
=> true
>> require './scrypt-1.4.0.jar'
=> true
>> java_import 'com.lambdaworks.crypto.SCryptUtil'
=> [Java::ComLambdaworksCrypto::SCryptUtil]
>> passwd,n,r,p = 'secret',16384,8,1
=> ["secret", 16384, 8, 1]
>> hashed_passwd = SCryptUtil.scrypt(passwd,n,r,p)
=> "$s0$e0801$MzcxaOBVz7kaVU6E5HV0cg==$RAx9ADWVeyZE5JRl+J1NpiBSEPNabEcVdR7drddpgMw="
>> SCryptUtil.check(passwd,hashed_passwd)
=> true
>> SCryptUtil.check('wrong password',hashed_passwd)
=> false

来晚了，我只是wrote a multi-platform gem which wraps up the details as an API drop-in replacement for the scrypt gem。

gem install scrypt-ruby -P MediumSecurity
