Installation

Using go install

go install github.com/Armageddon0x00/tckngen@latest

From Source

git clone https://github.com/Armageddon0x00/tckngen
cd tckngen
go install .

Usage

Generation

Generate 5 TCKN

tckngen generate 5

Generate 5 TCKN Without Banner

tckngen generate 5 nobanner

Generate Endless

You can pipe this to a file to generate example dataset.

tckngen generate endless nobanner

Validation

Validate Single TCKN

tckngen validate 12345678901

Validate All TCKN in File

tckngen validate exampleNumbers.txt

Only Show Valid TCKN in a File

tckngen validate exampleNumbers.txt valid nobanner

Only Show Invalid TCKN in a File

tckngen validate exampleNumbers.txt invalid nobanner

Same but in Bash

Validate and generate TCKN using Bash. Useful for offline and slow needs.

Validate TCKN Using Bash

tckncheck() {
  local RED="\e[31m"
  local ENDCOLOR="\e[0m"
  local GREEN="\e[32m"

  local TCKN="$1"
  local Pattern="^[0-9]{11}$"

  if [[ $TCKN =~ $Pattern ]]; then
    if [ "${TCKN:0:1}" -eq 0 ]; then
      echo -e "${RED} [-] TCKN not valid. $TCKN ${ENDCOLOR}"
    fi

    local odd=$(( ${TCKN:0:1} + ${TCKN:2:1} + ${TCKN:4:1} + ${TCKN:6:1} + ${TCKN:8:1} ))
    local even=$(( ${TCKN:1:1} + ${TCKN:3:1} + ${TCKN:5:1} + ${TCKN:7:1} ))
    local 10th_validator=$(( (odd * 7 - even) % 10 ))
    local sum=$(( (odd + even + ${TCKN:9:1}) % 10 ))

    if [ $10th_validator -ne ${TCKN:9:1} ]; then
      echo -e "${RED} [-] TCKN not valid. $TCKN ${ENDCOLOR}"
    fi

    if [ $sum -ne ${TCKN:10:1} ]; then
      echo -e "${RED} [-] TCKN not valid. $TCKN ${ENDCOLOR}"
    else
      echo -e "${GREEN} [+] TCKN is valid. $TCKN ${ENDCOLOR}"
    fi
  else
    echo -e "${RED} [-] TCKN not valid. $TCKN ${ENDCOLOR}"
  fi
}

Generate TCKN Using Bash

TODO

TODO

• Fix endless generation function (1/50000 error rate?)
• Add more validation options (only show valid - invalid)
• Improve generation algorithm (no duplicates in same generation, more randomness etc.)
• More parsing options
• Usable library functions ?
• KISS and Clean.
• Bash function for TCKN generation.

Sidenote: This was meant to be a simple hourly project. Now I'm invested.
