Ayke van Laethem	478c592b13	wasm: add support for the crypto/rand package ... This is done via wasi-libc and the WASI interface, for ease of maintenance (only one implementation for both WASI and JS/browsers).	2021-08-05 19:01:14 +02:00
Ayke van Laethem	d94f42f6e2	crypto/rand: replace this package with a TinyGo version ... This package provides access to an operating system resource (cryptographic numbers) and so needs to be replaced with a TinyGo version that does this in a different way. I've made the following choices while adding this feature: - I'm using the getentropy call whenever possible (most POSIX like systems), because it is easier to use and more reliable. Linux is the exception: it only added getentropy relatively recently. - I've left bare-metal implementations to a future patch. This because it's hard to reliably get cryptographically secure random numbers on embedded devices: most devices do not have a hardware PRNG for this purpose.	2021-06-21 18:22:31 +02:00
