HexToNsec converts a hex encoded secret key to a bech32 encoded nsec.

func HexToPublicKey

func HexToPublicKey(pk string) (p *ec.PublicKey, err error)

HexToPublicKey decodes a string that should be a 64 character long hex encoded public key into a ec.PublicKey that can be used to verify a signature or encode to Bech32.

func HexToSecretKey

func HexToSecretKey(sk string) (s *ec.SecretKey, err error)

HexToSecretKey decodes a string that should be a 64 character long hex encoded public key into a ec.PublicKey that can be used to verify a signature or encode to Bech32.

func NpubToPublicKey
