Online SHA384 Hash Generator

I have been given a set of steps to obtain a hash of data. I have trying to comprehend the steps for quite long now, but the hash that I am getting doesn't seem to match expected hash.

The steps that was mentioned is as follows:

1. Use the FIN message input as a binary value (unsigned char in C language, byte in Java). The FIN message input must be coded in the ASCII character set.
2. Combine the left LAU key and the right LAU key as one string. The merged LAU key must be used as a binary value (unsigned char in C language, byte in Java). The merged LAU key must be coded in the ASCII character set.
3. Call a HMAC256 routine to compute the hash value. The hash value must also be treated as a binary value (unsigned char in C language, byte in Java). The hmac size is 32 bytes.
4. Convert the hmac binary values to uppercase hexadecimal printable characters (for example, a onebyte binary value of 0000 1010 has a hexadecimal value of 0x0A and will be translated to the twobyte characters “0A”).

This is what I have tried.

It will be really helpful if someone can point whats wrong with the implementation.

I have three variables (password, nonce, and timestamp) and I need to get the value from them using this function:

Base64(SHA1($NONCE + $TIMESTAMP + SHA1($CLEARPASSWORD)))

My code in Postman is:

var clear_password = "AMADEUS";var nonce = "secretnonce10111";var timestamp = "2015-09-30T14:12:15Z";var crypto_pass = btoa(CryptoJS.SHA1(nonce + timestamp + CryptoJS.SHA1(clear_password)));

Using this values the result should be +LzcaRc+ndGAcZIXmq/N7xGes+k= but the real result is NWE1MGRhM2ZmNjFhMDA2ODUyNmIxMGM4MTczODQ0NjE2MWQyM2IxZQ==, and this result is like if I was doing:

Base64(HEX(SHA1($NONCE) + $TIMESTAMP + HEX(SHA1($CLEARPASSWORD))))

Is there any way to get the raw result from the SHA1 algorithm instead the HEX??

Thanks in advance.

EDIT

This is what I should to do, but I am stuck in the error of the third point:

I'm trying to pass a random string (which happens to be a number) "4176730.5" to SHA in Haskell to get a larger random string like "2d711642b726b04401627ca9fbac32f5c8530fb1903cc4db02258717921a4881".

I have this code to generate a random number and cast it to a string

  num <- randomIO :: IO Float  let x = C.pack (show (num*10000000))  print x

but when I pass it to SHA with

  let a = sha256 x

I get the error

Couldn't match expected type ‘Data.ByteString.Lazy.Internal.ByteString’            with actual type ‘C.ByteString’

I've tried casting my number to C.ByteString, but I think there are two types of Bytestring, according to the Haskell compiler.

The full code is:

import Data.Digest.Pure.SHAimport System.Randomimport qualified Data.ByteString.Char8 as Cmain :: IO ()main = do  num <- randomIO :: IO Float  let x = C.pack (show (num*10000000))  print x  let a = sha256 x      b = hmacSha256 "key" "some test message"  mapM_ print [showDigest a, showDigest b]

Seeing as how there are apparently two types of Bytestring, and I'm casting to the wrong one, how do I cast my random string correctly?

Further to @Cubic's answer below if I replace import qualified Data.ByteString.Char8 as Cwith

import qualified Data.ByteString.Lazy as C

I just get these errors

Couldn't match type ‘Char’ with ‘GHC.Word.Word8’Expected type: [GHC.Word.Word8]  Actual type: String

and

Couldn't match expected type ‘C.ByteString’            with actual type ‘[Char]’

I'm new to Python and I'm creating a login system that hashes the passwords with hashlib. I want to add easygui to the code but don't know how i'd go about it, i've imported easygui and have tried adding multipassword boxes and msgbox. However, everytime i try and implement the gui I always ruin my code, so its not able to read username or password.

Import hashlibfrom easygui import *username = ""def main():global usernameok, name, username = checkLogin()if ok:     print("Hello and Welcome to my Logon system", name.upper())     print("\n")     runMenu()else:    print("that is incorrect, please try again.") print("Thank you for using my system.")def checkLogin():    validUser = False    numAttempts = 0    while (not validUser) and numAttempts < 3:          uName = input("enter Username: ")          pWord = str(hashlib.sha256(input("enter password: ")encode()).hexdigest())if uName in users and pWord == users[uName]['pwd']:   validUser = True   return True, users[uName]['fName'], uNameelse:    numAttempts += 1if uName in users:    users[uName]['valid'] = "INVALID"return False

How would you guys go about adding easygui to this code?i've only imported easygui, as I'm confused on how to implement it so i get a username and password box that can verify the password. Also when the user logs in, a choicebox should appear:

def runMenu():    choice = ' '    choices = [None, addUser, changePassword, viewUserDetails, listAllUsers, remUser]while choice != '6':    choice = displayMenu()    if '1' <= choice <='5': choices[int(choice)]()    elif choice != '6' print("invalid input, please enter a number from 1 - 6." )with open('dict.txt', 'wb') as dataFile:     dataFile.write(encryptor.ecnrypt(str(users)))#end def

(The username and passwords are stored in a dictionary called dict.txt) Sorry if its confusing as its my first time on stackoverflow! :)

Thanks!

Through the use of openssl's sha 512 algorithm I'm currently able to calculate the hash of a 2GB file in between 3 - 3.3 seconds (my CPU is an i7-5820k) - including the time it takes to open, write to, and close files (open the input & write hash to text file).

I wondered if there are any known methods to speed this process up, or whether my HDD is entirely at fault, creating a bottleneck (Seagate BarraCuda Green 2TB 5900RPM SATA 6Gb/s 64MB Cache).

            FILE *ftest=fopen(hashInBuf, "rb");            FILE *ftest2=fopen(hashOutBuf, "wt");            //HASH FUNCTION            SHA512_Init (&mdContext);            while ((bytes = fread (data, 1, 1024, ftest)) != 0)            SHA512_Update (&mdContext, data, bytes);            SHA512_Final (c,&mdContext);            for(i = 0; i < SHA512_DIGEST_LENGTH; i++){              fprintf(ftest2, "%02x", c[i]);              printf("%02x", c[i]);

(the code I'm currently using to calculate the sha 512)
