Encryption / Decryption / Hashing Purpose Cryptography API: Next Generation (CNG) is Microsoft's long-term replacement for their CryptoAPI. CNG is designed to be extensible at many levels and cryptography agnostic in behavior. Although the Crypt.au3 UDF that is installed with AutoIt3 still works perfectly, the advapi32.dll functions that it uses have been deprecated. This UDF was created to offer a replacement for the deprecated functions. According to Microsoft, deprecated functions may be removed in future release. Therefore, this UDF will be available when/if that happens. Description This UDF implements some of Microsoft's Cryptography API: Next Generation (CNG) Win32 API functions. In its initial release, it implements functions to encrypt text & files, decrypt text and files, generate hashes, and the Password-Based Key Derivation Function 2 (PBKDF2) function. The UDF can implement any of the encryption/decryption algorithms or hashing algorithms that are installed on the PC in which it is running. Most, if not all, of the values that you would commonly use to specify that desired algorithms, key bit lengths, and other magic number type values, are already defined as constants or enums in the UDF file. To flatten the learning curve, there is an example file that shows examples of all of the major functionality. This example file is not created to be an exhaustive set of how to implement each feature and parameter. It is designed to give you a template or guide to help you hit the ground running in terms of using the functions. I have tried to fully document the headers of all of the functions as well as the code within the functions themselves. As of v1.4.0, there is also a Help file that includes all of the functions, with examples.

Hi all, I am working on a GUI program to update Google's Dynamic DNS (API at https://support.google.com/domains/answer/6147083?authuser=1&hl=en if you scroll to bottom). I am not a programmer by any means - just a sysadmin who has picked up on some things along the way. I am sure that there's better ways to do a lot of things in this script; I'm just going with what I know. My challenge right now is that I'd like a better way to store the credentials both in memory as well as in system registry or INI file (not sure which way I want to go for local storage). How should I convert the passwords to a secure string in a manner that can't be easily reversed, yet is still accessible to the script? Is that even an option in AutoIt? Can anybody provide me with links to good reference posts, or coding suggestions for how best to achieve this in the script below? I am using the WinHTTP UDF (https://github.com/dragana-r/autoit-winhttp/releases) to make my API calls. #include<WinHTTP.au3> #include<GUIConstantsEx.au3> #include<EditConstants.au3> #include<iNet.au3> #include<Array.au3> DIM $aDomainList[1][4] $aDomainList[0][0] = 0 $gMainGUI = GUICreate("Overkill's Google DNS Updater",800,800) $gDomainLabel = GUICtrlCreateLabel("FQDN",21,8) $gDomainInput = GUICtrlCreateInput("",60,5,300) $gUserLabel = GUICtrlCreateLabel("Username",5,36) $gUserInput = GUICtrlCreateInput("",60,32,130,Default,BitOR($GUI_SS_DEFAULT_INPUT,$ES_PASSWORD)) $gPasswordLabel = GUICtrlCreateLabel("Password",6,64) $gPassInput = GUICtrlCreateInput("",60,60,130,Default,BitOR($GUI_SS_DEFAULT_INPUT,$ES_PASSWORD)) $gAddButton = GUICtrlCreateButton("ADD DOMAIN",200,31,160,52) $gCurrentIP = GUICtrlCreateLabel("Current IP: " & _CheckIP(),5,780) $gDomainList = GUICtrlCreateListView("Domain | Resolved IP | Update Status",5,120,600,600) GUISetState(@SW_SHOW,$gMainGUI) while 1 $m = GUIGetMsg() IF $M = $GUI_EVENT_CLOSE then Exit IF $M = $gAddButton Then $sAddDomain = GUICtrlRead($gDomainInput) $sAddUser = GUICtrlRead($gUserInput) $sAddPass = GUICtrlRead($gPassInput) $sResolveIP = _DNSCheck($sAddDomain) ;Google wants you to avoid sending updates when there are no changes If StringCompare($sResolveIP,_CheckIP()) = 0 Then $sStatus = "No change, not sending update" Else $sStatus = _DNSUpdate($sAddDomain,$sAddUser,$sAddPass) EndIf ;Check to make sure all fields are completed before continuing IF StringLen($sAddDomain) = 0 OR StringLen($sAddUser) = 0 OR StringLen($sAddPass) = 0 Then MsgBox(0,"","Please complete all fields") Else ; If the fields all have data, then continue ;Check to see if the entry exists in the array already $iSanity = _ArraySearch($aDomainList,$sAddDomain) IF $iSanity = 0 Then _ArrayAdd($aDomainList,$sAddDomain & "|" & $sAddUser & "|" & $sAddPass ) If @error = 0 Then $aDomainList[0][0] += 1 $aDomainList[$aDomainList[0][0]][3] = GUICtrlCreateListViewItem($sAddDomain & "|" & $sResolveIP & "|" & $sStatus,$gDomainList) Else MsgBox(0,"","Error adding input to list") EndIf Else ; If $iSanity <> 0 ; Update existing info in array and listviewitem $aDomainList[$iSanity][0] = $sAddDomain $aDomainList[$iSanity][1] = $sAddUser $aDomainList[$iSanity][2] = $sAddPass GUICtrlSetData($aDomainList[$iSanity][3],$sAddDomain & "|" & $sResolveIP & "|" & $sStatus) EndIf ; If $iSanity = 0 EndIf ; If StringLen...
