5. // A secret key has no structure. It's nothing more than N bytes of data. // It should typically be random data, or bytes that resemble random data such // as the hash of a password. // The number of bytes in the secret key defines the bit-strength of an encryption // algorithm. For example, AES with a 32-byte key.

Description

Pseudo-Random Number Generator: A pseudo-random number generator, or PRNG, is a random number generator that produces a sequence of values based on a seed and a current state. Given the same seed, a PRNG will always output the same sequence of values.

The C library function int rand(void) returns a pseudo-random number in the range of 0 to RAND_MAX.

RAND_MAX is a constant whose default value may vary between implementations but it is granted to be at least 32767. Generate aes 256 encryption key.
