Show HN: Generate age encryption keys with custom prefixes Hello, I built a tool that generates age (modern file encryption https://ift.tt/DOfVI9S ) keys with vanity prefixes. The key innovation is using the fastest search algorithm available – it can check ~40'000'000 keys per second on a laptop, finding 6-character prefixes within a minute. For example, running `age-vanity-keygen hacker` will find a key like: $ age-vanity-keygen hacker Found age1hacker... in 23s after 973647953 attempts (42686172 attempts/s) # created: 2025-08-18T22:22:22+02:00 # public key: age1hackerxf9wukrzxfjt56xmq7c3y5ua5ylgrk0pmhlmdsg3773q8qh3ym6v AGE-SECRET-KEY-1K9G5Y6DRJPSXUFE2ELZULCG6SET7YC0676KR33WXSULW2CDHLGGS0EMJA2 The output is identical to the standard `age-keygen` tool, so it's a drop-in replacement when you want memorable or branded public keys. I've packaged it as both a Go binary and Docker image. The core algorithm is in a separate library ( https://ift.tt/AROcroK ) if anyone wants to use it for other X25519-based systems. Would love your feedback, thanks! https://ift.tt/6IBwoaR August 18, 2025 at 11:54PM
