std/hash

Usage

Creating new hash instance

You can create a new Hasher instance by calling createHash defined in mod.ts.

import { createHash } from "https://deno.land/std@$STD_VERSION/hash/mod.ts";

const hash = createHash("md5");
// ...

Using hash instance

You can use update method to feed data into your hash instance. Call digest method to retrive final hash value in ArrayBuffer.

import { createHash } from "https://deno.land/std@$STD_VERSION/hash/mod.ts";

const hash = createHash("md5");
hash.update("Your data here");
const final = hash.digest(); // returns ArrayBuffer.

Please note that digest invalidates the hash instance's internal state. Calling digest more than once will throw an Error.

import { createHash } from "https://deno.land/std@$STD_VERSION/hash/mod.ts";

const hash = createHash("md5");
hash.update("Your data here");
const final1 = hash.digest(); // returns ArrayBuffer.
const final2 = hash.digest(); // throws Error.

If you need final hash in string formats, call toString method with output format.

Supported formats are hex and base64 and default format is hex.

import { createHash } from "https://deno.land/std@$STD_VERSION/hash/mod.ts";

const hash = createHash("md5");
hash.update("Your data here");
const hashInHex = hash.toString(); // returns 5fe084ee423ff7e0c7709e9437cee89d
import { createHash } from "https://deno.land/std@$STD_VERSION/hash/mod.ts";

const hash = createHash("md5");
hash.update("Your data here");
const hashInBase64 = hash.toString("base64"); // returns X+CE7kI/9+DHcJ6UN87onQ==
