ConvertForBech32 performs the bit expansion required for encoding into Bech32.

ConvertFromBech32 collapses together the bit expanded 5 bit numbers encoded in bech32.

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

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.

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.

NpubToPublicKey decodes an nostr public key (npub) and returns an secp256k1 public key.

NsecToSecretKey decodes a nostr secret key (nsec) and returns the secp256k1 secret key.

PublicKeyToNpub encodes a public key as a bech32 string (npub).

SecretKeyToHex converts a secret key to the hex encoding.

SecretKeyToNsec encodes an secp256k1 secret key as a Bech32 string (nsec).

MinKeyStringLen is 56 because Bech32 needs 52 characters plus 4 for the HRP, any string shorter than this cannot be a nostr key.
