crypto
Usage
import { crypto } from "https://deno.land/std@0.146.0/crypto/mod.ts";
// This will delegate to the runtime's WebCrypto implementation.
console.log(
new Uint8Array(
await crypto.subtle.digest(
"SHA-384",
new TextEncoder().encode("hello world"),
),
),
);
// This will use a bundled Wasm/Rust implementation.
console.log(
new Uint8Array(
await crypto.subtle.digest(
"BLAKE3",
new TextEncoder().encode("hello world"),
),
),
);
Supported algorithms
Here is a list of supported algorithms. If the algorithm name in WebCrypto and Wasm/Rust is the same, this library prefers to use algorithms that are supported by WebCrypto.
WebCrypto
// https://deno.land/std/crypto/mod.ts
const webCryptoDigestAlgorithms = [
"SHA-384",
"SHA-256",
"SHA-512",
// insecure (length-extendable and collidable):
"SHA-1",
] as const;
Wasm/Rust
// https://deno.land/std/_wasm_crypto/mod.ts
export const digestAlgorithms = [
