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.

Features:

Supports 38+ modes/functions (see list below)
Encode / decode base64 & base58
Hex / dehex wordlists
Supports ASCII, UTF-8 and $HEX[] wordlist input

Useage Examples	Command Line
read wordlist.txt, hash to md5 and write to output.txt	./hashgen -m md5 -w wordlist.txt -o output.txt
pipe wordlist into hashgen and write to stdout	cat wordlist.txt \| ./hashgen -m md5
dehex wordlist to plaintext	./hashgen -m dehex -w hex_wordlist.txt
convert wordlist to $HEX[]	./hashgen -m hex -w wordlist.txt
output hash:plain	./hashgen -m md5 -w wordlist.txt -hashplain
benchmark md5	./hashgen -m md5 -w wordlist.txt -b

Supported Options:

Flag:	Description:
-m	{mode}
-w	{wordlist input}
-t	{cpu threads}
-o	{wordlist output}
-b	{benchmark mode}
-cost	{bcrypt}

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!

Compile hashgen from source:

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 repo
- cd hashgen # enter project directory
- go mod init hashgen # initialize Go module (skips if go.mod exists)
- go mod tidy # download dependencies
- go build -ldflags="-s -w" . # compile binary in current directory
- go install -ldflags="-s -w" . # compile binary and install to $GOPATH
Compile from source code how-to:

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!

hashgen v1.1.2 update:

In the tradition of keeping hashgen blazingly fast, I published an optimized implementation of base58 to GitHub:
https://pkg.go.dev/github.com/cyclone-github/base58

Switching hashgen's base58 encode/decode logic to cyclone/base58 gave a performance increase of 500%.

Key features of this base58 package:

Backwards compatible with other base58 packages using a familiar API based on Go's stdlib encoding/base64
Written in pure Go using stdlib with no external dependencies
Fast, efficient byte-based encoding/decoding
