Save crypted user email in database and use it for login in NodeJS

Question

Is it have any possible option to encrypt user email in nodejs (for security issue) and save it crypted in database(postgress). After that i use email for login and need to find user email in db. I try to encrypt with crypto, but every time hash is diffrent and I can't check it in db.

import crypto from 'crypto'
import fs from 'fs'
import { encryptText } from "./encrypt.mjs";


// The `generateKeyPairSync` method accepts two arguments:
// 1. The type ok keys we want, which in this case is "rsa"
// 2. An object with the properties of the key
const { publicKey, privateKey } = crypto.generateKeyPairSync("rsa", {
    // The standard secure default length for RSA keys is 2048 bits
    modulusLength: 2048,
})

const plainText = "[email protected]";

const encryptedText1 = encryptText(plainText)
// encryptedText will be returned as Buffer
// in order to see it in more readble form, convert it to base64
console.log('encrypted text: 1 ', encryptedText1.toString('base64'))

import fs from 'fs'
import crypto from 'crypto'

export function encryptText (plainText) {
  return crypto.publicEncrypt({
    key: fs.readFileSync('public_key.pem', 'utf8'),
    padding: crypto.constants.RSA_PKCS1_OAEP_PADDING,
    oaepHash: 'sha256'
  },
  // We convert the data string to a buffer`your text`
  Buffer.from(plainText)
  )
}
