用Ruby实现SJCL AES-128-CCM解密
用Ruby实现SJCL AES-128-CCM解密
提问于 2013-04-16 10:28:29
我正在尝试用Ruby实现aes-128-ccm加密字符串的SJCL解密。在阅读similar question之后，我发现新版本的OpenSSL库应该支持这一点，因此我已经将github的开发版本安装到了/opt上
这样做之后，当我运行/opt/bin/openssl ciphers时，我在列表中看不到aes-128-ccm密码：

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/我做错了什么？

好的，我已经成功了，下面是我所做的：
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现在使用某个目录中的共享库构建OpenSSL：
$ ./config shared --prefix=/home/jbr/local/openssl
$ make depend
$ make
$ make install确保您拥有ccm-support：
$ /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和新版本的OpenSSL安装一个命名的Ruby：
$ rvm install ruby-2.0.0-p195 -n ccm --with-openssl-dir=/home/jbr/local/openssl此命令将为您提供一个使用新OpenSSL库的Ruby2.0.0patch level 195版本，该版本使用了-ccm。
现在使用新版本的Ruby：
$ rvm use ruby-2.0.0-p195-ccm并使用irb进行测试：
$ irb
2.0.0p195 :001 > require 'openssl'
=> true
2.0.0p195 :005 > OpenSSL::Cipher.ciphers.include? "aes-128-ccm"
=> true 现在您有了aes-128-ccm。
