BrowserCrypto

Browser-backed implementation of Effect's Crypto service.

This module provides a Crypto.Crypto layer backed by the Web Crypto API. The WebCrypto context reference defaults to globalThis.crypto, so browser programs can use the standard implementation while tests or embedded runtimes can provide their own Crypto object.

Layers

layer

Added in v1.0.0 Source

Layer that directly interfaces with the Web Crypto API.

When to use

Use to provide cryptographic randomness, UUID generation, and digest operations in browser runtimes backed by globalThis.crypto.

Details

Random bytes are produced with crypto.getRandomValues. Digests are computed with crypto.subtle.digest and returned as Uint8Array values.

Gotchas

The layer dies if the Web Crypto object is unavailable. Digest operations fail with PlatformError when crypto.subtle.digest is unavailable or the browser rejects the digest request.

Signature

declare const layer: Layer.Layer<EffectCrypto.Crypto>;

Added in v1.0.0 Source
