#-------------------------------------------------------------------------
# Script Bash sederhana untuk mengecek nilai Hash pada sebuah File.
# Pembuat: Rofi (Fixploit03)
#
# Hash merupakan alat yang sangat berguna dalam menjaga integritas file, 
# memastikan bahwa data tetap utuh dan tidak mengalami perubahan yang 
# tidak diinginkan. Dengan memverifikasi hash, kita dapat mendeteksi
# manipulasi atau kerusakan file, sehingga keaslian dan keamanannya 
# tetap terjaga.
