Functions ¶

func Decrypt ¶

func Decrypt(key [32]byte, id, content []byte) ([]byte, error)

Decrypt derives the premary key with the given id and a random value. It reads the first bytes to get the derivation seed and tries to decrypt the content. Returns the aead.Open error if any.

func Encrypt ¶

func Encrypt(key [32]byte, id, content []byte) []byte

Encrypt derives the premary key with the given id and a random value. Returns the corresponding encrypted content with the random seed for derivation. The returned value can be decrypted by using the same key and id with Decrypt function.
