Functions

func Decrypt

func Decrypt(privKey libp2pc.PrivKey, ciphertext []byte) ([]byte, error)

func DecryptAES

func DecryptAES(bytes []byte, key []byte) ([]byte, error)

DecryptAES uses key (:32 key, 32:12 nonce) to perform AES-256 GCM decryption on bytes.

func Encrypt

func Encrypt(pubKey libp2pc.PubKey, bytes []byte) ([]byte, error)

func EncryptAES

func EncryptAES(bytes []byte, key []byte) ([]byte, error)

EncryptAES performs AES-256 GCM encryption on the provided bytes with key

func GenerateAESKey

func GenerateAESKey() ([]byte, error)

GenerateAESKey returns 44 random bytes, 32 for the key and 12 for a nonce.

func Verify

func Verify(pk libp2pc.PubKey, data []byte, sig []byte) error

verify verifies a signature
