## Examples
### ECB mode
```ts
import { Kalyna128, encryptECB, decryptECB } from "@li0ard/kalyna";

const cipher = new Kalyna128(hexToBytes("000102030405060708090A0B0C0D0E0F"));
const ct = hexToBytes("81BF1C7D779BAC20E1C9EA39B4D2AD06");
const pt = hexToBytes("101112131415161718191A1B1C1D1E1F");

console.log(encryptECB(cipher, pt));
console.log(decryptECB(cipher, ct));
```

### CBC mode
```ts
import { Kalyna128, encryptCBC, decryptCBC } from "@li0ard/kalyna";

const cipher = new Kalyna128(hexToBytes("000102030405060708090A0B0C0D0E0F"));
const iv = hexToBytes("101112131415161718191A1B1C1D1E1F");
const ct = hexToBytes("a73625d7be994e85469a9faabcedaab6dbc5f65dd77bb35e06bd7d1d8eafc8624d6cb31ce189c82b8979f2936de9bf14");
const pt = hexToBytes("202122232425262728292A2B2C2D2E2F303132333435363738393A3B3C3D3E3F404142434445464748494A4B4C4D4E4F");

console.log(encryptCBC(cipher, pt, iv));
console.log(decryptCBC(cipher, ct, iv));
```
