chacha20

✓ github.com/aead/chacha20

Encrypt data using ChaCha20 with a 64-bit nonce.

package main import ( "fmt" "github.com/aead/chacha20" ) func main() { key := make([]byte, 32) nonce := make([]byte, 8) cipher, err := chacha20.NewCipher(key, nonce) if err != nil { fmt.Println(err) return } src := []byte("hello") dst := make([]byte, len(src)) cipher.XORKeyStream(dst, src) fmt.Println(dst) }

Debug

Known issues

breakingNonce must be unique per key; reuse breaks security.

fix

Always use a fresh nonce for each encryption with the same key.
