WebFor example, assume we need a secret key, that will protect our financial assets.This secret key should be randomly generated in a way that nobody else should be able to generate or have the same key. If we generate the key from a secure random generator, the it will be unpredictable and the system will be secure. Therefore "secure random" means simply … WebCryptographically strong bytes are suitable for high integrity needs, such as long term key generation. If your generator is using a software algorithm, then the bytes will be pseudo-random (but still cryptographically strong). RAND_bytes returns 1 …
