JRuby的捆绑安装不宝石“scrypt”

Question

工作我试图做一个捆绑安装的JRuby（Windows）和我收到此错误：

我已经安装了JRuby和JVM。

Answer 1

你试图安装红宝石的Java版本内原生扩展宝石：通常是一个糟糕的主意......

我发现在https://github.com/wg/scrypt 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需要代码中的jar。

接下来是编写一个包装来模仿scrypt行为，将它用作ruby/rails代码中的插入替换。

或者，您可以直接删除scrypt位并使用java库。下面是jirb（1.7.20）测试的一个片段：

>> 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

这是晚了，但我只是wrote一个多平台gem它包装起来的细节作为API下拉更换为scrypt gem。

gem install scrypt-ruby -P MediumSecurity
