Crate bitwarden_random 

Bitwarden Random

Provides an abstraction to provide the single rng impl for the sdk. This can be seeded if the dangerous-seeded-rng-for-testing feature is enabled, but by default uses the OS CRNG.

Modules

ffi 🔒

Cross-platform (WASM / UniFFI) bindings for random-number generation.

seeded 🔒

Deterministic, seeded RNG support for tests/benches.

snow_resolver 🔒

Structs

SdkCryptoResolver

A snow [CryptoResolver] that supplies the SDK’s SdkRngImpl

SdkRandomNumberClient

Client exposing random-number generation to cross-platform bindings.

SdkRngImpl

The default Bitwarden RNG.

Enums

GenBytesError

Error returned by SdkRandomNumberClient::gen_bytes.

GenRangeError

Error returned by SdkRandomNumberClient::gen_range.

Inner 🔒

Scene

A named, reproducible RNG scene for tests. Each variant maps to a fixed seed.

Constants

UNIFFI_META_CONST_NAMESPACE_BITWARDEN_RANDOM 🔒

Export namespace metadata.

Traits

SdkRng

Marker trait for random number generators usable within the Bitwarden SDK.

Functions

clear_seed

Removes any thread-local seed, reverting crate::rng to the OS entropy source on this thread.

rng

Returns an SdkRngImpl. Mirrors [rand::rng] for ergonomic drop-in replacement.

rng_set_scene

Seeds the current thread’s RNG with the deterministic seed for the given Scene.

set_seed_raw

Sets up a deterministic, seeded ChaCha8 stream for the current thread. Where possible, the higher level rng_set_scene should be used instead.
