Hi,

The CryptGenKey function[^] and the other Cryptography Functions[^] are exported from Advapi32.dll and you can use them on OS WINVER >= 5.0

You should consider rephrasing your question... there are several different types of cryptography keys. If you are looking for a simple random sequence of bytes then perhaps the CryptGenRandom function[^] will do. The rand() function supposedly generates a relatively predictable sequence if an attacker knows the system time/uptime and other srand() input.
