Generate ECDSA keys
This procedure explains how to generate a pair of ECDSA keys with the P-256 (secp256k1) curve that you can use to sign and verify your JWTs.
-
Create a private key.
openssl ecparam -name secp256k1 -genkey -noout -out ec-secp256k1-priv-key.pem
Sample contents of the
ec-secp256k1-priv-key.pem
private key in PEM format:-----BEGIN EC PRIVATE KEY----- MHQCAQEEIEYgBlyQVsH7SpHUH7x4RErcckhu7ary/JjhP72Nk19EoAcGBSuBBAAK oUQDQgAE1MtHIxlGP5TARqBccrddNm1FnYH1Fp+onETz5KbXPSeG5FGwKMUXGfAm SZJq2gENULFewwymt+9bTXkjBZhh8A== -----END EC PRIVATE KEY-----
-
Create a public key by extracting it from the private key.
openssl ec -in ec-secp256k1-priv-key.pem -pubout > ec-secp256k1-pub-key.pem
Sample contents of the
ec-secp256k1-pub-key.pem
public key in PEM format:-----BEGIN PUBLIC KEY----- MFYwEAYHKoZIzj0CAQYFK4EEAAoDQgAE1MtHIxlGP5TARqBccrddNm1FnYH1Fp+o nETz5KbXPSeG5FGwKMUXGfAmSZJq2gENULFewwymt+9bTXkjBZhh8A== -----END PUBLIC KEY-----
