# HMAC-SHA-256 and HMAC-SHA-512 for AssemblyScript

Self-contained implementations of SHA-256, SHA-512, HMAC-SHA-256 and HMAC-SHA-512 for AssemblyScript.

Simple hashing:

```typescript

let msg = Uint8Array.wrap(String.UTF8.encode("test"));

let h = Sha256.hash(msg);

```

Chunked input:

```typescript

let st = new Sha256();

st.update(msg1);

st.update(msg2);

let h = st.final();

```

HMAC:

```typescript

let msg = Uint8Array.wrap(String.UTF8.encode("message"));

let key = Uint8Array.wrap(String.UTF8.encode("key"));

let mac = Sha256.hmac(msg, key);

```

Constant-time check for equality:

```typescript

let ok = verify(mac, expected_mac);

```

Constant-time hexadecimal encoding/decoding:

```typescript

let hex = bin2hex(h);

let bin = hex2bin(hex);

```
