Rand (Random)
This package is an extension to math/rand, providing cryptographically secure random numbers.
The interface of this package adopts math/rand/v2 and is forward compatible to Go 1.12
This package cannot directly replace math/rand or math/rand/v2, you need to write new code to use this library
RNG (Random Number Generator)
This package uses math/rand as the RNG.
In Go 1.22 and later versions, math/rand/v2 is used as the RNG.
