.net - C# - CryptographicException "Bad Hash" -

-

मुझे क्रिप्टोग्राफिक एक्सपैशन "Bad Hash। \ R \ n" प्राप्त हो रहा है जब मैं कॉल करता हूं CreateSignature । क्या यह हो सकता है के रूप में किसी भी विचार?

<पूर्व> RSAPKCS1 साइन-इनफ़ॉर्मर आरएसएफ़ॉर्मर = नया RSAPKCS1 साइन-इनफ़ॉर्मर (नया आरएसएक्र्रीपटोसेवाप्रॉवर्स ()); RSAFormatter.SetHashAlgorithm ( "SHA256"); बाइट [] हस्ताक्षरित हैश = आरएसएफ़ॉर्मर.खेलसाक्षर (मेरेहाश);

आपका कोड स्निपेट नहीं दिखाता कि आप कैसे मेरे होश लेते हैं लेकिन मेरा अनुमान यह है कि यह एक 32 बाइट सरणी नहीं से:

SHA256 एल्गोरिथ्म के लिए हैश का आकार 256 बिट्स है।

इस तरह से अपने myHash को परिभाषित करने का प्रयास करें: (यहां सिर्फ एक बदसूरत नमूना है) 

  // 256 बिट हैश आकार बाइट [] myHash = {59,4,248,102,77,97,142,201, 210,12,224,93,25,41,100,197, 210,12,224,93,25,41,100,197, 213,134,130,135, 213,134,130,135};

जब मैंने किसी भी अन्य आकार के हैश के साथ अपना कोड चलाया तो मुझे एक ही सटीक त्रुटि मिली 256 बिट या 32 बाइट्स से ऊपर परिभाषित सरणी के साथ चल रहा है, यह काम करता है।

paypal - How to know the URL referrer in PHP? -

-
I'm new to integrating PayPal with sites, so easily from the service I can use Can the available method be? What am I trying to do, when the user clicks on "Return to my website", I want my return URL to know that the referrer is PayPal so I can send it automatically to the homepage . how to do this? I tried $ _ SERVER ['HTTP_REFERER'] but it does not seem like anything. During the IPN conversation I set the cookie and session (though I am not sure whether I am correcting it or doing this right), but on returning to my website, it does not seem to recognize any session . If I use it by using $ _ SERVER ['HTTP_REFERER'] , then I'm afraid it's a security risk, is not it? If so, is there any other way I remember? help please. Should you really know the referrer? Set the PayPal Return URL to a "secret" URL which is always redirected to the homepage. If someone reaches there and gets redirected without coming from PayPal, then ...

wpf - Line breaks and indenting for the XAML of a saved FlowDocument? -

-
Is there a way to format XAM generated when a flow document is saved? Currently, all of this is run simultaneously in one line, and I want to break it into my elements, with line break and indenting it makes it a little easier to read. Here is the code I'm using to save a FlowDocument in a WPF RichTextBox as a XAML file: // entire document around TextRange textRange Create a TextRange side = new TextRange (myRichTextBox.Document.ContentStart, myRichTextBox.Document .contentEnd); // save the file using the file (file stream fs = file. Create (filename)) {textRange.Save (fs, DataFormats.Xaml); } Savings work fine, but as I mentioned, JPAM has been generated, all this goes together, no indentation or line breaks for its various elements Is: & lt; Section xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xml: space = "preserve" Tekstelinement = "left" Lainhait = "auto" Hashipineshn = enabled = "false...

oauth - Facebook OAuth2 Logout does not remove fb_ cookie -

-
This is used to work so I'm not sure what's wrong the user just logs in to Facebook properly Is capable of Logging problem. I log out the user logout by redirecting them to the php script. $ facebook-> GetLogoutUrl (); When users click on that link, they are logged out from the Facebook page. However, when they return to my site, I find that the FB_ cookie is still there. PHP SDK still gives user FB session details. The strange thing is that www.facebook.com shows that I am already logged out of Facebook. What can be wrong here? Thanks, I've been stumped: (. OK, finally, what did I do? > GetLogoutUrl () with a next = address url on my logout script which will remove the Facebook cookie by setSession (null) .
