encryption - 48-bit blowfish -

-

क्या एक ब्लॉफिश एल्गोरिदम का एक कार्यान्वयन (जावा / सी ++ / रूबी) है जो 48-बिट डेटा ब्लॉक का समर्थन करता है? मेरे पास एक एन्क्रिप्शन समस्या है जहां इनपुट और आउटपुट चैनल बिल्कुल 48 बिट्स हैं I नेट पर सभी कार्यान्वयन 64-बिट ब्लॉक के लिए हैं।

ऐसा इसलिए है क्योंकि 64 का एक सेट ब्लॉक आकार -bits। आप अपने डेटा के अंत में दो यादृच्छिक बाइट पैड कर सकते हैं। 

  'rubygems' की आवश्यकता होती है 'crypt / blowfish' bluffish = crypt :: blowfish.new ("56 बाइट्स तक की कुंजी ") सादा =" 123456 "एन्क्रिप्टेड ब्लॉक्ॉक = ब्लॉफ़िश.एन्क्रिप्ट_ब्लॉक (सादा + (रैंड (250) +5) .सीआर + (रैंड (250) +5) .सीआर)

या यदि आपका < कोड> सादा 6 बाइट्स / 48 बिट्स से कम हो सकता है 

  एन्क्रिप्टेड ब्लाक = ब्लॉफ़िश.एन्क्र्रीप्ट_ब्लॉक (सादे.लॉज़ (8))

Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
