30 second loop generating code

[arrowgent]

to ease the process and timing of generating codes based on steam's generation @ :00 seconds and :30 seconds

here is a bash script with some rudimentary code to loop the process

enter your required variables at the top
then chmod +x steamguard-cli.sh
then ./steamguard-cli.sh
it will loop every 30 seconds and copy the key to the clipboard

#!/bin/bash

#timer 30 seconds
#steamguard-cli uses SDA (windows) maFiles manifest (see .wine)


#your maFiles location
MAFILES="/home/$USER/.local/bin/steamguard-cli/maFiles"

#your passkey or decryption if required (should be required)
STEAMGUARD_CLI_PASSKEY=$(cat /A/TEXT/FILE/DIR/OR/OTHER/ENCRYPTION/METHOD/p.txt)

#obvious your steam username
USERNAME="YOUR USERNAME"

while true; do
# do code first time
exec /home/$USER/.local/bin/steamguard-cli/steamguard -m $MAFILES -u $USERNAME -p $STEAMGUARD_CLI_PASSKEY code | xclip -selection clipboard
echo "copied to clipboard";
xsel -b;

#first date in seconds
timer=$(date +%S)
#always true date = less than :60
    while [ $timer -le 60 ];
    do
# check date timer for :00 or :30 to start new code
            if [[ "echo $timer" =~ "00"|"30" ]];
            then
                exec /home/$USER/.local/bin/steamguard-cli/steamguard -m $MAFILES -u $USERNAME -p $STEAMGUARD_CLI_PASSKEY code | xclip -selection clipboard
                echo "generating new key";
                echo "copied to clipboard";
                xsel -b;
#new date seconds
timer=$(date +%S)
                echo $timer;
# timeout 30 seconds
                sleep 1;
            else
#new date seconds
timer=$(date +%S)
                echo $timer;
# seconds interval loop
                sleep 1;
            fi
    done
done

also noting it takes 5-7 seconds to generate a key using steamguard-cli

You can use --offline to speed up code generation. By default, steamguard-cli reaches out to valve servers to get the time because the user's clock might be wrong.

awesome thanks. that will be faster than asking steam for the time. my time is always updated

checking with --offline it still seems to take about 6 seconds
not sure why it needs this extra time

the SDA seems to happen instantly on :00 and :30 rollover, maybe it is pre-emptively generating the code

Using encryption will make it take longer to generate codes because steamguard-cli has to decrypt the appropriate file every time it is run, and the encryption is slow because of the PBKDF2 iterations.

steamguard-cli/src/encryption.rs

Line 66 in db6557c

const PBKDF2_ITERATIONS: u32 = 50000; // This is excessive, but necessary to maintain compatibility with SteamDesktopAuthenticator.

Also IIRC steam does give you some leeway with the codes it accepts. I think it'll accept the previous code and the current code in case the user is too slow typing it in.
