js和java的DES对有中文的文本加密结果不一样，求解决！
同样一个含有中文文本 在js加密和java加密是得到不一样的结果没有中文时候结果是一样的 我想请问怎么怎么解决呢是不是js需要编码了 才能加密一样？只要能把{"pwd":"123123","username":"张无忌","cell":"18475556059"} 用js加密出来 成Mc开头 和java一样就行了 先谢过了！
js和jar文件在这里

des针对的的bytes,java中的String.getbytes不带参数,默然使用本地语言,你可以加参数试试.
js不了解,只要两个语言从string到bytes是一样的,结果才可能一样
看js好像是toutf8的,你在java里也使用getbytes("utf8")试试 @鬼哥 希望鬼哥帮忙看看 rover12421 发表于 2015-4-1 00:33

好的 我还有一个问题 是这样的 我的win8 32 位 安装了1.75的java sdk 用了eclipse 对AES 16位的key 不能进行加密 你可以帮我看看 是什么原因？
