Post subject:  i need help! i would like to encrypt pass
currently in my login script, my password is numeric only, i would like to make it alphanumeric, with letters, to encrypt it, i would like to turn it into numbers using strint, but every attempt i have done failed, after useing strint, i would mess with the numbers and put it into a file, then i would unmess the numbers and use intstr

my question, how would i use strint and instr because it wont work for me

well intstr() and strint() just work with integers. alphanumerics wouldn't do..

although encryption is done as ASCII value level, so you should look into ord() and chr()

Or, if you want to get very inventive....setup a little code system.
like:
code:

a= 294
b= 148
c= 492
y=283
h=193
p=934
.....
4= dkj
8= awe

So make a character equal to a random three (or more) digit number, and a number equal to a three letter nonsensive word. Record all these, when you save into to a file (for ex a game) do something like this
(Assuming my char name is Cabby and password equals bach4)
Filename= 'Cabby.sav'
Encrypted File:
[FILE]
492 294 148 148 283
148 294 492 193 dkj
[END FILE]
De-encrypted File:
[FILE]
c a b b y
b a c h 4
[END FILE]

Get what I mean? It would take quite awhile for someone (for whatever reason) who wanted to hack through your encrypted file. The more digits, the harder Wink .
And to read this...do something like this:
code:

var code:array 1..20 of string
var datafile:int:=0
var temp,encrypt:string:=""
open:datafile,"cabby.sav",get
for i:1..eof(datafile)
get:datafile,temp(i)
encrypt+=temp
end for
for i:1..length(encrypt)
code(i):= /*blah blah*/
end for

I dont wanna give it all away, so basically...if you want to encrypt it, that method works.
