Functions

func DecryptStringWithKey

func DecryptStringWithKey(data, key []byte) ([]byte, error)

DecryptStringWithKey decrypts data using secretbox with the provided key

func EncryptWithKey

func EncryptWithKey(data, key []byte) ([]byte, error)

EncryptWithKey encrypts data using NaCl's secretbox with the provided key. 40 bytes of overhead (24-byte nonce + 16-byte MAC) are added to the plaintext size.

func GenerateKey

func GenerateKey() ([]byte, error)

GenerateKey generates a random 32-byte key to be used by EncryptWithKey and DecryptWithKey
