how to generate pssh for this kid?

Find the script for converting KID to PSSH. There should be available in this forum.
And this is the KID: e1ffaf848b627e31b5eb17d635f3aed4

import base64

def get_pssh(keyId):
    array_of_bytes = bytearray( b'\x00\x00\x002pssh\x00\x00\x00\x00')
    array_of_bytes.extend(bytes.fromhex("edef8ba979d64acea3c827dcd51d21ed"))
    array_of_bytes.extend(b'\x00\x00\x00\x12\x12\x10')
    array_of_bytes.extend(bytes.fromhex( keyId.replace("-", "")))
    return base64.b64encode(bytes.fromhex(array_of_bytes.hex()))

kid = input("Please input KID in hex string from C4: ")
kid = kid.replace(' ', '')
kid = kid.replace('-', '')
assert len(kid) == 32 and not isinstance(kid, bytes), "wrong KID length"
print("PSSH {}".format(get_pssh(kid).decode('utf-8')))
