Password encryption sha1 php to node js crypto

Question

I have this two function in php.

public function hashSSHA($password) {
    $salt = sha1(rand());
    $salt = substr($salt, 0, 10);
    $encrypted_password = base64_encode(sha1($password . $salt, true).$salt);
    $hash = array("salt"=>$salt, "encrypted"=>$encrypted_password);
    return $hash;
}

//Password Decryption 
public function checkhashSSHA($salt, $password) {
    $hash = base64_encode(sha1($password . $salt, true).$salt);
    return $hash;
}

I am trying to write this two functions in node js.

Here is something I tried.

const hash = crypto.createHash('sha1', 'my different salt from DB');
hash.update(password);
console.log(hash.digest('base64'));

But they both produced different results.

These Node.js functions should be equivalent to your PHP code:

const crypto = require("crypto");

function hashSSHA(password){
    let salt = crypto.createHash('sha1').update(crypto.randomBytes(8)).digest('base64');
    salt = salt.substring(0,10);
    const hash = crypto.createHash('sha1');
    hash.update(password + salt);
    return {
        salt: salt,
        encrypted: Buffer.concat([hash.digest(), Buffer.from(salt)]).toString('base64')
    };
};

function checkhashSSHA(salt, password) {
    const hash = crypto.createHash('sha1');
    hash.update(password + salt);
    return Buffer.concat([hash.digest(), Buffer.from(salt)]).toString('base64');
}

const password = "some password";
const hashResult = hashSSHA(password);
console.log("Hash result: ", hashResult);
console.log("Check hash result: ", checkhashSSHA(hashResult.salt, password));
