simple nostr vanity address generator

nostrogen.com

this is a simple vanity key generator for the nostr protocol. choose prefix or suffix, enter allowed characters in the input, and press generate. your keys/addresses will then be generated in the container below for you to copy and save.

here are some example generated address pairs. don't use these ones if you don't want others to also have access. generate your own instead and store them securely.

prefix: pre

the characters have to be in the bech32 character set.

this depends entirely upon how fast your machine is, but here are some rough estimates for a modern laptop or mobile phone:

1 character = usually less than a 0.1 seconds
2 characters = usually less than a 1 second
3 characters = usually less than a 30 seconds
4 characters = usually less than a 10 minutes
5 characters = usually less than a 1 hour
6+ characters = keep fire extinguisher handy

nah, but- don't trust, verify. check out the code on github, ask a programmer friend, or- if you're really paranoid, download the source and run this program on a clean computer without internet access. these are just nostr keys though, not bitcoin keys..
