specified path directory Value hash

Hi,

This script is used to calculate the hash values for a directory using SHA256, SHA1 and MD5.

Edit Parameters:

directory=r"C:\Users\Peacock\Downloads"#mention your directory here
option='3' # provide option for selecting the operation to perform
#option 1: For Calculating the Hash value for a directory using Sha256
#option 2: For Calculating the Hash value for a directory using Sha1
#option 3: For Calculating the Hash value for a directory using MD5

Run as System User
