Functions

func New

func New(key *ecdsa.PrivateKey, pub *ecdsa.PublicKey, salt []byte, padding int, hashfunc func() hash.Hash) (encryption.Interface, error)

New constructs an encryption interface (the modified blockcipher) with a base key derived from a shared secret (using a private key and the counterparty's public key) hashed with a salt

func NewDecrypter

func NewDecrypter(key *ecdsa.PrivateKey, pub *ecdsa.PublicKey, salt []byte, hashfunc func() hash.Hash) (encryption.Decrypter, error)

NewDecrypter constructs an el-Gamal decrypter the receiving party uses the public key must be the ephemeral return value of the Encrypter constructor

func NewEncryptor

func NewEncryptor(pub *ecdsa.PublicKey, salt []byte, padding int, hashfunc func() hash.Hash) (encryption.Encrypter, *ecdsa.PublicKey, error)

NewEncryptor constructs an El-Gamal encryptor this involves generating an ephemeral key pair the public part of which is returned as it is needed for the counterparty to decrypt
