🚀 Oh wow, another #deep #dive into #Elixir, the #programming language nobody asked for. 🌿 #Consistent hashing! Because who doesn’t want their life to revolve around distributing weights like they’re some kind of modern-day Hercules? 💪 Let’s all pretend we're excited about Elixir’s quest to solve problems nobody has. 🎉

Can there be a #password #hashing algorithm that considers the distance between each character key on a keyboard (of some specific layout, say QWERTY)? The difficulty of hitting the correct character on a small 26-key on-screen keyboard on my phone is making me think whether we should have a relaxed algorithm that gives some fault tolerance... (Surely it'll not be as secure, but it could allow longer passwords on phones.)

To manage passwords in #golang, check out the following #gogen packages:

* Generate new #passwords: https://pkg.go.dev/github.com/tecnickcom/gogen/pkg/random.
* Check for #similarity with existing passwords: https://pkg.go.dev/github.com/tecnickcom/gogen/pkg/stringmetric.
* Compare passwords against #compromised ones (#pwned): https://pkg.go.dev/github.com/tecnickcom/gogen/pkg/passwordpwned.
* Secure password #hashing, #storage, and #verification: https://pkg.go.dev/github.com/tecnickcom/gogen/pkg/passwordhash (based on #OWASP Password Storage Cheat advice).
