The method explained in the extra file is how to encrypt, you need decrypt, so you must reverse the method.

You will need know the ascii:

[quote=CRYPT V1] 1. Re-number all visible ascii characters, so ! will now be
1 instead of 33 and “ will be 2 instead of 34 and so on

  1. Get each letter of your string and do the following:
    a: Get its new ascii code value
    b: Take this value, and subtract it from the total
    number of visible ASCII characters
    c: Get the character at this position
    d: Get this characters original ascii value

  2. Put all these values in a csv e.g. 61,72,71[/quote]

Help me clear some doubt

  1. Get each letter of your string and do the following:
    a: Get its new ascii code value // based on Rule 1
    b: Take this value, and subtract it from the total
    number of visible ASCII characters // So visible ASCII chars which i have in my string or that in the table?
    c: Get the character at this position // From ASCII table or from my input string?
    d: Get this characters original ascii value

Any help will be appreciated :D

Visible chars are about the ascii table and the position is just to convert to ascii values in order.

Hi to all :) I read all discussions about this chall. Feel i’m quite near to the resolution. I would like to send to someone who already solved it my Python3 script for a check… Anyone available, maybe?
