idk theres probably some basic stuff out there that does everything visually but u won't be able to program much

you know the 'codes' arent really that difficult, just try to think very literally and mathematically. example from VB:

If md5(textbox1.text) = str.md5pass
Grant_Login()
End If

damn i don't even know if that's correct i havent used VB in ages
anyway:

If md5(textbox1.text) = str.md5pass  -»  If the MD5 hash of the text in textbox1, is the same as the string str.md5pass, then:
Grant_Login()  -» Do whatever you say in the sub called "grant_login"
End If  -» Ur done here, now do the next stuff
