A generator of random bool, int, or double values.
The default implementation supplies a stream of pseudo-random bits that are not suitable for cryptographic purposes.
Use the Random.secure() constructor for cryptographic purposes.
Constructors
- Random([int seed ])
-
Creates a random number generator.
factory - Random.secure()
-
Creates a cryptographically secure random number generator.
