生成的种子值AES密钥 [英] Generate AES key with seed value
问题描述
如何生成种子值AES密钥，这样每当我生成相同的种子值的关键，我shud能够得到相同的AES密钥？
How do I Generate AES key with seed value so that whenever I generate key with same seed value,I shud be able to get the same AES key?
我要生成此键为我的黑莓珍珠8100设备。
I want to generate this key for my Blackberry Pearl 8100 device.
我不能够产生与AESKey（KEYDATA）AES密钥。
I am not able to generate AES key with AESKey(keyData) .
此外，每当我打印出来无论是在字符串或形式的byte []，我不能够生成它。（打印）实际密钥从不打印。
Also whenever I print it either in the form of String or byte[] , I am not able to generate it.(print it) Actual key is never printed.
可以做些什么来得到钥匙？
What can be done to get the key?
更新
我试图通过传递字节[我的资料]，如follws产生AESKey：
I tried generating AESKey by passing byte[] of my data,as follws:
AESKey key = new AESKey(keyData);
每次我得到相同的密钥，这是正确的。
Everytime I get same key, which is correct.
现在使用这个键，我加密加密我，我得到的加密不同的价值data.Everytime。这里是我的问题。我怎样才能得到加密后的数据相同每次，这样我就可以将其发送到服务器？
Now using this key I am encrypting the data.Everytime I encrypt I get different value of encryption. Here is my problem. How can I get same data everytime after encryption,so that I can send it to server?

推荐答案
第5.2节中 RFC 2898 描述了这样的一种方式。
Section 5.2 in RFC 2898 describes one way of doing this.
具体地讲，种子值由一个密码短语和盐的;但考虑到相同的密码和盐，总是会导致相同的密钥。
Specifically, the "seed" value consists of a "PASSPHRASE" and a "SALT"; but given the same passphrase and salt, will always result in the same key.
