Generate Public and Private Keys

Generate an Ed25519 key pair to use as the API Key and API Secret.
  1. In a terminal, run the following OpenSSL commands:
# Generate a private key and save it in the `private.key.pem` file.
openssl genpkey -algorithm ed25519 -out private_key.pem

# Extract the public key from the private key and save it in the `public.key.pem` file.
openssl pkey -in private_key.pem -pubout -out public_key.pem
The private key is saved in private.key.pem, and the public key is saved in public.key.pem.
  1. You can print the keys by running the following commands:
# Export the private key in hexadecimal format.
openssl pkey -in private_key.pem -text | grep 'priv:' -A 3 | tail -n +2 | tr -d ':\n '

# Export the public key in hexadecimal format.
openssl pkey -pubin -in public_key.pem -text | grep 'pub:' -A 3 | tail -n +2 | tr -d ':\n '
