WebRAND_bytes will fetch cryptographically strong random bytes. Cryptographically 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 for success, and 0 otherwise. WebSHA-2 is widely used by developers and in cryptography and is considered cryptographically strong enough for modern commercial applications. SHA-256 is widely used in the Bitcoin blockchain, e.g. for identifying the transaction hashes and for the proof-of-work mining performed by the miners.
