JAVA 使用DES加密字符串,windows系统和linux系统加密后不一样

[「已注销」]

以下同样的代码在windows系统和linux系统加密出来的字符串不一样，
请问是什么问题导致的？

byte[] 	getBytes()
Encodes this String into a sequence of bytes using the platform's default charset, storing the result into a new byte array.

Win默认GBK，Linux默认UTF-8

[huntor]

strKey.getBytes() 方法使用默认的编码返回，Win和linux默认编码不一样

引用 2 楼 huntor 的回复:

不是这个问题，在AIX系统试的，系统的默认编码就是GBK。 而且对于数字来说，UTF-8和GBK编码都是一样的。
