Question

我正在尝试为jruby（Windows）进行捆绑安装，我收到此错误：

我已经安装了jruby和JVM。

你正试图在java版本的ruby中安装带有原生扩展的gem：通常是一个坏主意......

我在https://github.com/wg/scrypt找到了scrypt算法的纯java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需要jar。

接下来是编写一个包装器来模仿scrypt行为，将其用作ruby / rails代码中的替代品。

或者，您可以删除scrypt位并直接使用java库。这是在jirb（1.7.20）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

Answer 2

已经很晚了，但我只是wrote一个多平台gem，它将详细信息作为scrypt gem的API替代品替代。

gem install scrypt-ruby -P MediumSecurity

jruby bundle安装不在gem＆＃39; scrypt＆＃39;
