hash

hash(value) returns the WebCrypto digest of value as a lowercase hex string. It is async — crypto.subtle.digest returns a promise — so await the result. Pass a different algorithm name as the second argument to switch from the default 'SHA-256'.

Part of pota/use/string; pairs well with copyToClipboard.

Arguments

Argument	Type	Description
value	string	The string to digest.
algo	string	Algorithm name passed to WebCrypto. Defaults to SHA-256.

Returns: Promise<string> — the digest as a lowercase hex string.

Examples

Digest a string

Hashes a value with the default SHA-256, then again with SHA-1.

import { hash } from 'pota/use/string'

const digest = await hash('hello') // 64-char SHA-256 hex string
const sha1 = await hash('hello', 'SHA-1') // 40-char SHA-1 hex string
