TOTP issue

[Mem5]

Hi all,
I generate a TOTP PIN thanks to python lib, using 'hashcat' password.

Code:

import pyotp

# base32_encode(hashcat) = NBQXG2DDMF2A====

totp = pyotp.TOTP("NBQXG2DDMF2A====")
print(totp.at(1572603245)+":1572603245")

test.hash contains PIN + timestamp:

915418:1572603245

I launch:

hashcat -m 18100 -a 3 -o res.txt test.hash ?l?l?l?l?l?l?l

Status : cracked, result is :

915418:1572603245:MJQXE3TDNZYA====

But

base32_decode(MJQXE3TDNZYA====) = barncnp

which is not the password 'hashcat'..

using hashcat-5.1.0+1409

Thanks for your help.
