Functions

func RecoverSecp256PublicKey

func RecoverSecp256PublicKey(cert *x509.Certificate) ([]byte, error)

Recover the secp256k1 public key using RSA public key and the signature This is the reverse what has been done in RsaPrivateKeyToSecp256PrivateKey It returns the marshalled public key

func RsaPrivateKeyToSecp256PrivateKey

func RsaPrivateKeyToSecp256PrivateKey(rPrivKey *rsa.PrivateKey) *secp256k1.PrivateKey

Takes a RSA privateKey and builds using it's hash an secp256k1 private key.

func SignRsaPublicKey

func SignRsaPublicKey(privKey *secp256k1.PrivateKey, pubKey *rsa.PublicKey) *pkix.Extension

Sign a rsa public key with the given secp256k1 private key and return a x509 Extension. The secp256k1 public key can be recovered for e.g. nodeId
