Generate Private Bytes (CSPRNG)

Randomly generates the specified amount of bytes using a separate Cryptographically Secure Pseudo-Random Generator
instance supplied by OpenSSL. It is intended to be used for generating values that should remain private.

Note: By default, OpenSSL CSPRNG supports security level of 256 bits.
However, security depends on the entropy source.
For more information read https://www.openssl.org/docs/man1.1.1/man3/RAND_bytes.html.

Inputs

In Exec
Num Integer	the amount of bytes to generate.

Outputs

Out Exec
Error Message String	if an error occured, the error message.
Bytes Array of Bytes	if generation was successful, the generated bytes.
Success Boolean	True if generation was successful, false otherwise
