java - Using Sun JCE provider on top of IBM SDK -

-

I have to use Sun JCE Provider in an application that runs on the IRB webserfare. This can be achieved by specifying security_provider.1 = com.sun.crypto.provider.SunJCE. Some parts of my application use IBM's SSL features. I

I want to know that the SunJCE provider Configuring affects other uses of the JSAE provider in my application.

I want to ask that the second question is, is there any way to continue using IBM JDK defaults (JCE and LTSJSE and others) and use only Sun JCE wherever needed. I mean that I will configure the Sun JCE provider as a previous security_provider.10. And in the code base where I need to use Sun JCE provider, I will clearly provide the provider name in my crypto related classes. Pre cipher sip = cipher For Gate Instance ("DES", "Sun") ..

Please tell me what is the best way.

To specify a security provider, you should do what you said: 

  cipher sip = cipher Gate Instance ("DES", "Sun")

But Sun is named "SunJCE", IBM is "IBMCeE", you can also use third-party providers as Bayerci Castell You can. You should take care of the "provider knotfond" exception.

This sun will use the implementation: 

  cipher cip = cipher .get instance ("DES", "sunseye")

This will use the IBM implementation: 

  cipher cip = cipher .get instance ("DES", "IBSEE")

If you use IBM SDK Using, it will do the same: 

  cipher cip = cipher By the way, if you install (security edits) SDK files), as the last provider, the Sun is the provider, which in any way affects your application. Because when you search for an algorithm, the JCE API will look for the first provider examples, then for the second, and so on (when this algorithm is found, it stops).

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
