Validator node registration values

Setup

You will need to generate three values to register the node with the system:

• 20-byte node id bytes in hex
• raw certificate bytes in hex
• signature bytes in hex

On your validator node locate the certificate (.crt) and private key (.key) file. The usual locations are:

• ~/.avalanchego/staking/staker.key
• ~/.avalanchego/staking/staker.crt

The combination of following values will be needed for all three steps. You can set them for your current shell process by copy pasting the following snippet into your terminal.

PATH_TO_CRT=~/.avalanchego/staking/staker.crt
ZERO_PREFIX=0000000000000000000000000000000000000000000000000000000000000000
PATH_TO_KEY=~/.avalanchego/staking/staker.key
IDENTITY_ADDRESS=youridentityaddresswithout0xprefix

20-byte node id bytes in hex

NOTE: If you have older version of openssl, try without -provider legacy.

cat $PATH_TO_CRT | \
  tail -n +2 | \
  head -n -1 | \
  base64 -d | \ 
  openssl dgst -sha256 -binary | \
  openssl rmd160 -provider legacy -binary | \
  xxd -p | \
  sed -e 's/^/0x/;'

Raw certificate bytes in hex

cat $PATH_TO_CRT | \
  tail -n +2 | \
  head -n -1 | \
  base64 -d | \
  xxd -p | \
  tr -d \\n | \
  sed -e 's/^/0x/;' && echo

Signature bytes in hex

echo -n $ZERO_PREFIX$IDENTITY_ADDRESS | \
  xxd -r -p | \
  openssl dgst -sha256 -sign $PATH_TO_KEY | \
  xxd -p | \
  tr -d \\n | \
  sed -e 's/^/0x/;' && echo
