Online SHA384 Hash Generator

I want to use k-anonymity to retrieve a set of breached passwords from HIBP. For that, I made a fetch request to the API with the first five SHA1-enciphered chars of the password in the following way:

const passBox = document.getElementById("passBox");let passCompromised = document.getElementById("passCompromised");passBox.addEventListener("keyup", keyupEvent);function keyupEvent(event) {    event.preventDefault();    if (passBox.value !== "" && (event.key === "Enter" || event.which === 1)) {        isPassBreached();    }}function status(response) {    if (response.ok) {        return response.text();    } else if (response.status === 404) {        return [];    } else if (response.status === 400) {        alert("Bad request");        return response.text();    } else {        throw new Error(response.statusText);    }}function isPassBreached() {    let passPlain = "";    passPlain = passBox.value;    let passSHA1 = SHA1(passPlain);    passSHA1 = passSHA1.toUpperCase();    let strPassSHA1 = passSHA1.substring(0, 5);    fetch("https://api.pwnedpasswords.com/range/" + strPassSHA1)        .then(status)        .then(breaches => {            breaches.forEach(check => {            let responseHTTP = check;            console(responseHTTP);            if (responseHTTP.indexOf(strPassSHA1) !== -1) {                let passList = responseHTTP.split("\n");                let pwnedCount = 0;                let i = 0;                let timeSpell = "times";                for (i; i < passList.length; i++) {                    if (strPassSHA1 == passList[i].split(":")[0]) {                        pwnedCount = passList[i].split(":")[1];                        if (passlist[i].split(":")[1] == 1) {                            timeSpell = "time";                        }                    }                }                passCompromised.innerHTML = "This password was found <b>" + pwnedCount + "</b> " + timeSpell + ' in compromised databases! If this is your password, you should change it immediately. Use a <a href="https://www.pcmag.com/article2/0,2817,2407168,00.asp" target="_blank" rel="noopener">password manager.</a></span>';            } else {                passCompromised.innerHTML =                    "Good news, this password has never been breached!";            }        });    });}

However, when I test the code on codepen, I receive the following error: Uncaught (in promise) TypeError: breaches.forEach is not a function. I figured that it's due to the fact that, first, my status function returned response.json() promises so I changed that to text ones, following this guideline, but that didn't help. What am I doing wrong?

Note: the SHA1 JS algorithm can be found here (not posted due to brevity).

this block content in sha 1 is bothering me.616263 was referring to abc in hex, follow by 80...on the 16th line it has a value of 18.

since block content starts with 0. as I count sha 1 only upto 448 bits have abc as 24 bits then need 424.so 448 / 8 = 56 / 5 = 11.2 or 12so how did it become 16 containers?Block Contents:

W[0] = 61626380W[1] = 00000000W[2] = 00000000W[3] = 00000000W[4] = 00000000W[5] = 00000000W[6] = 00000000W[7] = 00000000W[8] = 00000000W[9] = 00000000W[10] = 00000000W[11] = 00000000W[12] = 00000000W[13] = 00000000W[14] = 00000000W[15] = 00000018<blck content/>

SHA-1 produces a 160-bit (20-byte) hash value known as a message digest – typically rendered as a hexadecimal number, 40 digits long, so is this (20-byte) of hex value as an array or just normal hex value?

This is my code: so what is the datatype of the output:

import java.security.MessageDigest; public class MessageDigestExample {public static void main(String[] args)throws Exception{String input = "This is a message";MessageDigest hash = MessageDigest.getInstance("SHA1");System.out.println("input : " + input);hash.update(Utils.toByteArray(input));System.out.println("digest : " + Utils.toHex(hash.digest()));

} }

I have this hex array of 20 Byte which the output [Digest] of SAH-1:

b1d5781111d84f7b3fe45a0852e59758cd7a87e5 

How can I reuse it as 16 Byte to be the initialize IV in AES_CBC encryption algorithm as this:

0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00 

I am new in programming. I am creating a website using django-python. I want to store data in MySQL with encryption. Can I use SHA-3 for encryption? Is it the most secure hashing algorithm currently? Or which encryption method should I choose to encrypt data?
