[原]oxygen.xml.editor.8.2.keygen&patch

今天下了一个好插件,处理xml的,注册机混淆了,研究了下jvm的opcode,把oxygen的xml editor(eclipse plugin)注册机发上来,
只要把plugin下的oxygenEclipse.jar中的ro.sync.D.A.class反编译一下,替换里边的数组为注册机中的数组,这个注册机就能用了.代码:

ps:今天上午又看了下注册原理,其实就是A.class里边是公钥,注册时程序将注册码base64decode为密文,然后再用公钥解开,明文内容应该和注册名一致;
而注册码是作者用用户的注册名+作者的私钥生成的.
因此只需要用程序生成一对密钥,私钥放入keygen里边,公钥放入A.class里边覆盖原来的公钥byte[],就ok了.这次终于明白签名注册的原理了 :-)
