Functions

func CreateKey

func CreateKey(size int) ([]byte, error)

CreateKey returns a valid key (secret) of a certain size, to be used when encrypting/decrypting AES.

This function should be used by applications importing this lib. E.g by servers where the key must be known to the clients where encryption is involved.

func Decrypt

func Decrypt(key, message []byte) ([]byte, error)

Decrypt returns the decrypted message where the provided key must be the same key used when encrypting the message.

func Encrypt

func Encrypt(key, message []byte) ([]byte, error)

Encrypt returns the encrypted message where the provided key has been used during encryption.

Types
