From 6b5634b96aa90ab2db7357b353fc8f96ad4878c5 Mon Sep 17 00:00:00 2001 From: Fabio Alessandrelli Date: Mon, 7 Feb 2022 17:33:55 +0100 Subject: [OS/Crypto] Add get_entropy to OS. Implemented via `BCryptGenRandom` on Windows. Implemented via `getentropy` syscall when available. Implemented via `/dev/urandom` device as a fallback. The `/dev/urandom` fallback can be disabled via the `NO_URANDOM` build flag. Note: The HTML5 version relies on emscripten file system urandom device which itself uses the Crypto API when available or the plain old not crypto-safe `Math.random()` otherwise. Restore get_entropy. --- core/os/os.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'core') diff --git a/core/os/os.h b/core/os/os.h index d3d2a868fa..188900a070 100644 --- a/core/os/os.h +++ b/core/os/os.h @@ -132,6 +132,8 @@ public: virtual String get_stdin_string(bool p_block = true) = 0; + virtual Error get_entropy(uint8_t *r_buffer, int p_bytes) = 0; // Should return cryptographically-safe random bytes. + virtual PackedStringArray get_connected_midi_inputs(); virtual void open_midi_inputs(); virtual void close_midi_inputs(); -- cgit v1.2.3
