Overview

Example

if !common.Available {
	return
}
key := make([]byte, KeySize)
rand.Read(key)
aead, err := New(key, 16)
if err != nil {
	panic(err)
}

nonce := make([]byte, aead.NonceSize())
rand.Read(nonce)

ciphertext := aead.Seal(nil, nonce, []byte("hello, world!"), nil)

plaintext, err := aead.Open(nil, nonce, ciphertext, nil)
if err != nil {
	panic(err)
}

fmt.Println(string(plaintext))

Output:

hello, world!
