Generate random bytes and numbers with OpenSSL
this set of functions generates random bytes or numbers from OpenSSL. This
provides a cryptographically secure alternative to R's default random number generator.
rand_bytes generates n random cryptographically secure bytes
rand_bytes(n = 1) rand_num(n = 1)
n |
number of random bytes or numbers to generate |
