问题描述
我想知道是否有一种使用 PBEKeySpec 和字节数组参数的方法。
I would like to know if there is a way to use PBEKeySpec with a byte array argument.

推荐答案
由于Java PKCS＃5 KeyFactory 已指定为只使用低8位的 PBEKeySpec 中的字符，您应该能够将字节数组转换为（16位）字符数组，而不会出现问题。
As the Java PKCS#5 KeyFactory has been specified to only use the lower 8 bits of the characters in the PBEKeySpec, you should be able to convert your byte array into a (16 bit) character array without issue. Just copy the value of each byte into the character array and you should be set.
只要确定，我会执行 charArray [i] = byteArray [i]& 0xFF 作为赋值语句，否则你将得到非常高的字符。
Just to be sure, I would perform charArray[i] = byteArray[i] & 0xFF as assignment statement, otherwise you would get very high valued characters.
这是一个丑陋的解决方法，但我没有看到任何理由它不应该工作。
It's an ugly workaround, but I don't see any reason why it should not work.
请注意，上述假设。如果你允许代码点0x80到0xFF，那么你不能使用UTF-8（或UTF-16当然）作为编码。
Note that the above assumes Latin / Windows 1252 compatible encoding for values 0x80 and over. If you allow code points of 0x80 to 0xFF then you cannot use UTF-8 (or UTF-16 of course) as encoding.
