Example Usage

python3 id_hash/identify_hash.py --value-file id_hash/known.txt --hash-file id_hash/hash.txt --try-external --external-verbose --john-fork 28

If you are going to user --john-fork

Please understand what your processor is capable of. The system this was tested on can --fork to 32; however, that would make the system come to a halt.

The --value-file

This file can be the output from the burp extension at https://github.com/awillard1/burp-extensions/blob/main/id_hash.py or https://github.com/awillard1/burp-extensions/blob/main/id_hash_advanced.py

The file could also be any wordlist you want to use against the --hash-file.

Run the following to see how many threads your system is capable of:

cat /proc/cpuinfo | grep processor | wc -l

Ubuntu Directions

1) System essentials (build tools only needed if a wheel isn’t available)

sudo apt update
sudo apt install -y python3 python3-pip python3-venv build-essential python3-dev libffi-dev

2) External tools

sudo apt install -y hashcat

3) Python packages (local algs + extras used by the script)

python3 -m pip install --upgrade pip setuptools wheel
python3 -m pip install blake3 pycryptodome "passlib[bcrypt,argon2]" mmh3 xxhash

(Optional) If you ever had the old, incompatible PyCrypto:

python3 -m pip uninstall -y pycrypto

Installing JTR

1) Build deps (CPU-only)

sudo apt update
sudo apt install -y build-essential git pkg-config libssl-dev zlib1g-dev yasm \
                    libgmp-dev libpcap-dev libbz2-dev libzstd-dev libkrb5-dev

Optional (GPU/OpenCL support — if you have GPU drivers set up)

sudo apt install -y ocl-icd-opencl-dev opencl-headers

2) Get source

git clone https://github.com/openwall/john.git
cd john/src

3) Configure & build (CPU-only)

./configure
make -s clean && make -sj"$(nproc)"

4) Symlink 'john' onto your PATH so you don’t need the full path (the compiled binary lives in ../run/john)

sudo ln -sf "$(pwd)/../run/john" /usr/local/bin/john

5) Verify

john

The result may look something like:

John the Ripper 1.9.0-jumbo-1+bleeding-2694ea3f98 2025-09-26 18:17:10 +0200 OMP [linux-gnu 64-bit x86_64 AVX2 AC]

OpenSSL

Create a config (user-scoped is fine), e.g. ~/.config/openssl/openssl.cnf:

openssl_conf = openssl_init

[openssl_init]
providers = provider_sect

[provider_sect]
default = default_sect
legacy  = legacy_sect

[default_sect]
activate = 1

[legacy_sect]
activate = 1
