Hi Cybro0, thanks for your interest in CLAASP! Indeed, the docker image should simplify the installation, and our recommendation is to do that. Note that we are also working on a web application that will allow to access CLAASP with no need of installing anything beside the Chrome browser. We hope to have this available by early 2024. If you really want to go for the full local installation, please let us know and we can try to debug your issue. |

I have 32 bit value in t3 variable and i have to pass it through S-Box. Question is, How do i take this 4 8-bit values as one string or one value in a variable.

Hi,
I will suggest to check to use the intermediate output components. You can
see some examples of them in almost of the ciphers that are implemented in
claasp. For example, in Speck.

Specifically, in the file speck_block_cipher.py. If it is the last round
also you can use the “cipher output component”. Again you can see several
examples of how to use this in almost of the cipher implemented in claasp.

Yes, that is for last resultant. But in my case, it is in middle of the round function , as i need to pass the S-Box substituted string to the rotate component. How do i do without the output component |

Hi Cybro,
In that case you can use the add_round_output_component component. Since
you need to pass the S-Box substituted string to the rotate component then
you can also directly use the rotate component without using the
add_round_output_component. To do so you need to use the input_id_links
parameter of add_round_output_component. Check the attached image.

Hi Cybro0,
If I understood well you need to do something similar to what is done in
slide 3 of
https://askworkshop.github.io/ask2023/assets/accessory/ASK_slides-juan.pdf.
Please check it and let me know if that help.

My scenario as i pasted my screenshot is, I'm getting last 8 bits of my
S_Box output passed to rot component. I have to change my code lines
accordingly to get whole S-Box substituted string passed to rot component.
How can i do that?

I tried as you done in 7th slide (ToySPN1). But, im getting error of " the length of [input_bit_positions] is not equal to input_bit_size ". |

I think that your issue is due the second parameter must be a list of sub
lists and each Sublist must contain the indexes. In your case each sublist
has again a list.

Good that now it is working. Regarding this second issue. It seems you are
using the constant component. If so, could you please share the line

In at least one of your calls to add constant component you’re not passing
the parameters correctly. Check them again. It seems is something similar
to your previous issue.

Hi, I opted for manual installation which I cloned the git, and next command is to run the "configure. sh" file. Then I noticed that it doesn't have execute permission. So I chmod it and after running the script. I got the error as this: "dependencies_script.sh" permission denied. How to resolve this?. or should I go for docker installation?
