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). 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.

Features:

• Maintains original input order PR 10
• Supports 60+ 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

Benchmarks:

• https://github.com/cyclone-github/hashgen-testing/tree/main/benchmarks
• 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!

Antivirus False Positives:

• 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.

Thoughts:

• 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:
  • https://github.com/cyclone-github/hashgen-testing
• 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!
