不过经过自己这两天的探索，嘿嘿。还是搞定了。。。 现在和大家分享~！
先说说加密的代码位置：
（从安装目录开始）atlassian-jira/WEB-INF/lib/atlassian-osuser-1.1.1.jar
很多文件都是 class 文件，我就是直接用 JD 打开的。进行反编译。
打开 atlassian-osuser-1.1.1.jar ， 依次打开 com.opensymphony.user.provider.ejb.util 。
Base64.java 和 PasswordDigester.java 就是给用户密码加密的代码了。
不过 JD 反编译出来的 PasswordDigester.java 有问题。后来去网上查了资料替换了原来的代码。我贴在下面了。。。
