Hi, I need your help. I have a certificate, it is also installed in my PC Windows Server 2003. I would like to use this to sign a timestamp response using CryptSignHash function of MS CryptoAPI. The signature generated by this function is also reversed byte-order (because of the litle

It just occurred to me that the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\RNG\Seed (type REG_BINARY) contains the latest seeded value from everything that CryptoAPI takes into account when generating its random seed. CryptoAPI permutes it with RC4 to come up with a pseudo

ng issues mean MS hasn't actually exposed the raw RSA routines: you can't for example encrypt and decrypt arbitrary data using RSA and CryptoAPI. This means it isn't a case of simply replacing the OpenSSL RSA routines with CryptoAPI, you'd also need to replace digests and symmet

Has anyone out there used the WIN32 OpenSSL toolkit in conjunction with the Microsoft Cryptography API ? By doing this you avoid any copyright problems from RSA because Microsoft has licensed the RSA code and placed in the Windows 95/98 and Windows NT operating systems. Does anyone know how co
