@se-oss/sha1 is an isomorphic SHA-1 hashing library that automatically leverages native performance in Node.js while providing a robust pure-JS fallback for browsers.

npm install @se-oss/sha1

pnpm install @se-oss/sha1

yarn add @se-oss/sha1

Calculate the SHA-1 hash of a string. Returns a Uint8Array.

import { sha1 } from '@se-oss/sha1';

const hash = sha1('password');
// Uint8Array(20) [ 91, 170, 97, 228, ... ]

Support for Uint8Array or Buffer as input.

import { sha1 } from '@se-oss/sha1';

const data = new TextEncoder().encode('hello world');
const hash = sha1(data);

The library detects the environment and switches implementations automatically:

• Node.js: Uses node:crypto for hardware-accelerated performance.
• Browsers/Edge: Uses a pure JavaScript implementation.

For all configuration options, please see the API docs.
