How Can I Encript String To SHA-1 Using Javascript OR Jquery?

I want to hash a simple string with SHA-1 hash function using javascript.

Solution 1:

In a browser, you can use SubtleCrypto.digest, which returns a Promise:

crypto.subtle.digest('SHA-1', arrayBuffer);

In node.js you can use crypto.createHash:

const crypto = require( 'crypto' );
const hash = crypto.createHash('sha1');
const result = hash.digest(buffer);

Browser demo:

logSha1( 'foobar' );

async function logSha1( str ) {
  const buffer = new TextEncoder( 'utf-8' ).encode( str );
  const digest = await crypto.subtle.digest('SHA-1', buffer);

  // Convert digest to hex string
  const result = Array.from(new Uint8Array(digest)).map( x => x.toString(16).padStart(2,'0') ).join('');

  console.log( result );
}
