PowerShell password complexity test with regular expressions

#RegEx for password for CMatch (Case-Sensitive match)
# * Must have at least one digit
# * Must have at least one alhabetical symbol in lower case
# * Must have at least one alhabetical symbol in upper case
# * Must be at least 8 characters long
# (!) Warning, regex uses LookBehind logic. Google for "RegEx LookBehind"
$regEx = '^(?<PASS>.{8,})(?<=.*[A-Z].*)(?<=.*[a-z].*)(?<=.*[0-9].*)$'
