Introduction
In the history of Internet development, security has always been a topic that developers pay great attention to. To ensure data transmission security, we need to ensure that data sources (non-counterfeit requests), data integrity (not modified), Data Privacy (ciphertext, cannot be directly read), etc. Although the SSL

factors must be used as seeds. OpenSSL has made efforts internally, but we recommend that you add a random factor before generating a function using a random number.
The rand_add () function can add random factors to the internal state. Then, you can use rand_bytes () to obtain the random number.
Void rand_add (const void * Buf, int num, double entropy );
Int rand_bytes (unsigned char * Buf, int num );
