问题 All of the examples I have seen end up converting a SecureString back to a standard string before using it, defeating the object. What's a good way of using a secure string without this problem? I know I can marshall the SecureString to a BSTR but what can I do with this BSTR? Can I get the characters back one at a time? If so, how? 回答1: This link includes a lot of helpful information, including how to get an unmanaged memory block for passing the string to native code (that is presumably

问题 Is there a way to decrypt PBKDF2 password in java. Java has implementation of PBKDF2 algorithm as PBKDF2WithHmacSHA1 . I got the code to create hashes for password.

问题 So I'm making an app where I want the users to be able add, edit and rate content, but I do not want to force them to register. Instead I was planning on just using their device id or device token to identify them. I'm planning on making both an iPhone and Android version, so I'm looking for a general solution, but the iPhone version has higher priority, so an iPhone specific solution would also be welcome. The problem is that I don't want just anyone to be able to use my web service by

问题 I have an application that behaves oddly, and just to verify, I'd like to see which security zone it is currently running under.
