Using PowerShell, we can look in text files for strings that fit the criteria for passwords and return the potential password, file path, and line number. The criteria that is being search uses regex expressions and looks for at least four characters but no more than 15 with at least one character being upper, lower, a number, and a special character. The data is returned in a xml file and is best read back into PowerShell using out-gridview (my fav.). The code is on my GitHub located HERE.
