In my spare time I have implemented a simple Visual C++ application to show the power of Microsoft Crypt Library. The following functions have been implemented and tested using MD5 checksum and RC4 encryption/decryption:

• BOOL GetChecksumBuff er(ALG_ID nAlgorithm, LPBYTE lpszOutputBuffe r, DWORD& dwOutputLength, LPBYTE lpszInputBuffer , DWORD dwInputLength);
• BOOL GetChecksumStri ng(ALG_ID nAlgorithm, CString& strResult, CString strBuffer);
• BOOL

INTRODUCTION
The Secure Hash Algorithm 2 is a series of cryptographic hash algorithms designed by the US National Security Agency (NSA) and published by the National Institute of Standards and Technology (NIST) as a government standard.

There is currently a competition being held by NIST to find a new family of algorithms for what will be named SHA-3. These new functions may not necessarily be derived from the SHA-2 algorithms....

Description
RC4 is one of the most widely used ciphers in the world. It is used in WEP, WPA, SSL, BitTorrent, PDF, etc. It is one of the simplest to understand and implement. It is also one of the fastest algorithms available.

What is RC4
It is a stream cipher, which means that it encrypts a stream of data byte by byte as opposed to a block cipher that encrypts groups of bytes at a time, usually with the inclusion of...

Hi,

I have a doubt about c# HashCodes. When I compare a string and get its hashcode an INT will be returned right? We all know that an int has 10 digits lenght. My doubt is about this int generated. I know that a string will always return the SAME hashcode AND the hashcode algorithm says the hashcode is not UNIQUE. So... do we have a chance to get different strings with the same hashcode??? Or there is a criptography behind the String...

This is driving me insane. Ive checked every sample and cant see anything happening differently. I'm sending the file over a network so the key and IV bytes are sent with the file to be used to decrypt, but every time it goes to decrypt i get "Padding is invalid and cannot be removed." Please give me at least a clue someone.

Edit : I know I posted this under the wrong language, my bad. Its c# not c

here's my code:...

hey ppl i jus wanna kno the basis of devising an encryption system to provide security at various levels... I jus wanna kno how to create an encryption system like 256 bit AES(Advanced Encryption System)!!!! Which programming must b known to create this??? What's the logic n where to start???? Please Help!!!!!!!!
