BruteForce

A simple brute force software written in GO

Usage

BruteForce --type [md5|sha256|sha512|sha1|bcrypt|ripemd160] --value <hash>

Example:

./BruteForce --type sha256 --value 88d4266fd4e6338d13b845fcf289579d209c897823b9217da3e161936f031589

How to use a specific char set

If you want to use a specific set of chars, write it on a simple txt file and use the --alphabet option Example with a file alpha.data containing:

abcdefghijklmnopqrstuvwxyz

You can launch it with:

./BruteForce --alphabet alpha.data --type sha256 --value 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08
Start brute-forcing (sha256)...

How to use a dictionary file

If you want to use a file containing all words to be tested, write them on a simple file (one per line) and use the --dictionary option. Example with a file dic.data containing:

dragon
butterfly
test

You can launch it with:

./BruteForce --dictionary dic.data --type sha256 --value 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08

How to use a salt

If you want to use a salt you can simply add it with the salt parameter (before and/or after) Example:

./BruteForce --value cb2537e62f7f7358cb5b6a812c7d3c7d95d87733 --type sha1 --salt-after 1234567890
Start brute-forcing (sha1)...
Found: zzzz in 3 s

./BruteForce --value ef95124ec674cea240e9dd02c86ba3670e2ee5a2 --type sha1 --salt-before 1234567890
Start brute-forcing (sha1)...
Found: zzzz in 3 s

How to use size limit

If you want to control the size words generated, you can use the size parameter for a specific size or a range. Example:

./BruteForce  --type sha256 --value 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08 --size 4

Found: test in 2 s 

./BruteForce  --type sha256 --value 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08 --size 2-4

Gpu support (beta)

Use GPU support

Currently, only SHA-256 is supported with this option, and only for Windows and Linux builds, with an OpenCL compatible device and driver.

And if you want to use GPU to compute hashs, just use the GPU parameter:

./BruteForce --type sha256 --value 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08 --gpu

Found: test in 9 s

Build with GPU support

If you want to build with GPU support, you must use the command go build -tags opencl. You will also need header and lib files available.

• Linux : You just have to install the right package on your Linux system (example dnf install opencl-headers on Fedora)
• Windows : download the OpenCL package (https://github.com/GPUOpen-LibrariesAndSDKs/OCL-SDK/releases) and use GO flags CGO_CPPFLAGS=-I c:\OCL_SDK_Light\include and CGO_LDFLAGS=-L c:\OCL_SDK_Light\lib\x86_64. You might also need gcc, I use the package from https://jmeubank.github.io/tdm-gcc/ but it should work with any version.
