我正在尝试在Ruby中实现aes-128-ccm加密字符串的SJCL解密。 在阅读了类似的问题之后,我看到这应该在较新版本的OpenSSL库中得到支持,所以我已经将开发版本从github安装到/ opt

执行此操作后,当我运行/ opt / bin / openssl密码时,我在列表中看不到aes-128-ccm密码:

我使用命令重新安装了ruby 2.0.0p0和rvm: rvm reinstall 2.0.0 --with-openssl-dir=/opt (在前面提到的文章中给出)。 然后运行cipher = OpenSSL::Cipher.new('aes-128-ccm') 其中返回了以下错误:

unsupported cipher algorithm (aes-128-ccm)

我的问题是如何在Ruby中添加对AES-128-CCM的支持/我在这里做错了什么?

===============>>#1 票数:2

好吧我已经成功了,这就是我做的:

首先从github获取OpenSSL源代码:

$ git clone https://github.com/openssl/openssl.git
$ cd openssl/

如果您想要与我使用的完全相同的版本,请执行以下操作:

$ git checkout 5ae8d6bcbaff99423a2608559d738a3fcf7ed6dc -b tmp

现在在某个目录中使用共享库构建OpenSSL:

$ ./config shared --prefix=/home/jbr/local/openssl
$ make depend
$ make
$ make install

确保你有ccm支持:

$ /home/jbr/local/openssl/bin/openssl enc -help  2>&1 | grep "ccm"
-aes-128-ccm               -aes-128-cfb               -aes-128-cfb1             
-aes-192-cbc               -aes-192-ccm               -aes-192-cfb              
-aes-256-ccm               -aes-256-cfb               -aes-256-cfb1   

好的,现在使用rvm和你的新版OpenSSL安装一个名为Ruby的软件:

$ rvm install ruby-2.0.0-p195 -n ccm --with-openssl-dir=/home/jbr/local/openssl

此命令为您提供了一个与-ccm混合的Ruby 2.0.0补丁级别195的版本,它使用您的新OpenSSL库。

现在使用新版本的Ruby:

$ rvm use ruby-2.0.0-p195-ccm

并用irb测试它:

$ irb
2.0.0p195 :001 > require 'openssl'
 => true
2.0.0p195 :005 > OpenSSL::Cipher.ciphers.include? "aes-128-ccm"
 => true 

你现在有aes-128-ccm。
