Random Number Generation

@deprecated
def add(buffer: bytes, entropy: int) -> None:
    """
    Add random bytes to OpenSSL's entropy pool.
    
    Parameters:
    - buffer: Random bytes to add to entropy pool
    - entropy: Estimate of entropy in buffer (in bytes)
    
    Note: This function is deprecated. Modern OpenSSL versions
    automatically seed the random number generator.

    Check if random number generator has been seeded.
    
    Returns:
    1 if PRNG has been seeded with enough data, 0 otherwise
    
    Note: This function is deprecated and may not provide
    meaningful results on modern systems.
