Overview

Key-Convertr

People are copy-pasting nostr private keys into webpages to convert between the original hex-encoding and bech32-encoding (specified in NIP-19).

This is kind of bonkers, so here's a command-line utility that you can run to convert public/private keys between hex-encoding and the NIP-19 bech32 encoding. IT can also convert note id's.

To use it, you need cargo installed. Then from the key-convertr directory, just do cargo install --path .. It will put a program called key-convertr in your $HOME/.cargo/bin directory.

Then, to convert from a hex-encoded pubkey to a bech32-encoded pubkey, you can do

$> key-convertr --kind npub 3bf0c63fcb93463407af97a5e5ee64fa883d107ef9e558472c4eb9aaaefa459d
npub180cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwsyjh6w6

Just provide the hex-encoded key or note-id and a --kind argument. The kinds supported are:

  • npub
  • nsec
  • note

To convert from an npub to hex-encoding, you can do

$> key-convertr --to-hex npub180cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwsyjh6w6
