As of the this writing, hashgen (go) has a 2,519% faster md5 hashrate vs the next fastest publicly available CPU based hash generator (see benchmarks). While this is extremely fast, these hashrates can be beat by improved code optimization and/or coding in faster programming languages (I'm looking at you C, Rust and Zig).
Since version v2023-10-30.1600, hashgen has a top recorded hasharate of 30,228,048 md5/sec on the test rig's Ryzen 7 3700X CPU! Much faster hashrates have been seen on higher end CPU's.
Hashgen is a CLI hash generator written in Go and can be cross compiled for Linux, Raspberry Pi, Windows & Mac, although testing and compiling is mainly done on debian 12 linux.
To use hashgen, type your mode, wordlist input & hash output files with a simple command line.
- Maintains original input order PR 10
- Supports 58+ modes/functions (see list below)
- Encode / decode base64 & base58
- Hex / dehex wordlists
- Supports ASCII, UTF-8 and $HEX[] input
- Supports UTF-8 (default) or $HEX[] output
- Supports multiple salted modes such as -m 110 / -m 120

- In addition to hashgen (go), I have also written hashgen in python, php, C, and Rust, although Rust and C need a lot of work to unlock their full performance potential. If you speak C or Rust, I'd be curious to see how fast you can push hashgen!
- If you want the latest features, compiling from source is the best option since the release version may run several revisions behind the source code.
- This assumes you have Go and Git installed
git clone https://github.com/cyclone-github/hashgen.git# clone repocd hashgen# enter project directorygo mod init hashgen# initialize Go module (skips if go.mod exists)go mod tidy# download dependenciesgo build -ldflags="-s -w" .# compile binary in current directorygo install -ldflags="-s -w" .# compile binary and install to $GOPATH

- Several antivirus programs on VirusTotal incorrectly detect hashgen as a false positive. This issue primarily affects the Windows executable binary, but is not limited to it. If this concerns you, I recommend carefully reviewing hashgen's source code, then proceed to compile the binary yourself.
- Uploading your compiled hashgen binaries to https://virustotal.com and leaving an upvote or a comment would be helpful.
- Why write hashgen? hashgen is nothing new (to me) as this project started several years ago while needing a way to quickly convert wordlists to md5 or sha1 on linux terminal. Several versions of hashgen have been written over the years in several languages: python, php, Go, C and Rust. While the actively maintained version is hashgen (go), which offers enhanced features and superior performance, the "hashgen-testing" repository linked below contains testing versions of hashgen in different programming languages:
- Why write hashgen in Go instead of xyz language? I did this to push my Go coding skills while also seeing how fast I could push Go. During early testing, I was not expecting hashgen to be all that fast, but I have been pleasantly surprised!
- When I realized hashgen (go) was competitively fast compared to other publicly available hash generators, I decided to publish hashgen's code and binaries for others to use. I've really enjoyed this project and I hope you find it useful.
- If you found hashgen to be helpful, please consider giving this repository a star!
