-
-`fastrand` implements a cryptographically secure pseudorandom number generator.
-The generator is seeded using the system's default entropy source, and
-thereafter produces random values via repeated hashing. As a result, `fastrand`
-can generate randomness much faster than `crypto/rand`, and generation cannot
-fail beyond a potential panic during `init()`.
-
-`fastrand` also scales better than `crypto/rand` and `math/rand` when called in
-parallel. In fact, `fastrand` can even outperform `math/rand` when using enough threads.

-## Security ##
-
-`fastrand` uses an algorithm similar to Fortuna, which is the basis for the
-`/dev/random` device in FreeBSD. However, although the techniques used by
-`fastrand` are known to be secure, the specific implementation has not been
-reviewed by a security professional. Use with caution.
-
-The general strategy is to use `crypto/rand` at init to get 32 bytes of strong
-entropy. From there, the entropy is concatenated to a counter and hashed
-repeatedly, providing 64 bytes of random output each time the counter is
-incremented. The counter is 16 bytes, which provides strong guarantees that a
-cycle will not be seen throughout the lifetime of the program.
-
-The `sync/atomic` package is used to ensure that multiple threads calling
-`fastrand` concurrently are always guaranteed to end up with unique counters.
