| ## Platform-Specific Default Random |
| |
| The implementation of the default random generator varies by platform. The implementation |
| on each platform must be thread-safe and automatically seeded, and should be |
| cryptographically secure to the extent possible. Currently supported platforms have the |
| following implementation details: |
| |
| - Apple platforms use `arc4random_buf(3)`. |
| - Linux, FreeBSD, and other UNIX-like platforms use `getrandom(2)` when available; |
| otherwise, they read from `/dev/urandom`. |
| - Fuchsia platforms use `getentropy(3)`. |
| - Windows platforms use `BCryptGenRandom`. |
