Password based encription script
Filed under: Scripts
This is a very nifty script i made up some time ago, what it does is to encript a given string (argument0) with a given password (argument1), it obviously returns the encripted string.
/* Encription basic code: -Arg0 = String -Arg1 = Password -Return = Cripted string By Manuel Etchegaray */ var n,nn,ch,r,ok,chp; r = "" for (n=1; n < string_length(argument0)-1; n+=1) { ch = ord(string_char_at(argument0,n)) ok = 0 for (nn=1; nn < string_length(argument1)+1; nn+=1) { chp = round(ord(string_char_at(argument1,nn))/nn) if n/nn = ceil(n/nn) and ok = 0 { r += chr(ch+chp)//To decript, just change this for: chr(ch-chp) ok = 1 } } if ok = 0 { chp = ord(string_char_at(argument1,nn)) r += chr(ch+chp)//To decript, just change this for: chr(ch-chp) } } return (r)
What it does exactly? it goes trough the whole string with a ‘for’ loop, changing the ASCII values of the characters based on the password ASCIII values (a simple password+character algorithm). This might sound simple, but i found it really hard to break ( if not impossible ), since you need to know the passoword to decript the text :)
