}
```

## Usage

```kotlin
import com.infendro.hash.`SHA-256`
import com.infendro.kdf.PBKDF2

fun main() {
    // create a PBKDF2 instance using HMAC SHA256
    //   this example uses 32 bytes of length and 100_000 iterations
    val kdf = PBKDF2(32, 100_000, `SHA-256`)

    // securely hash value with some salt
    val value = "password".encodeToByteArray().asUByteArray()
    val salt = "salt".encodeToByteArray().asUByteArray()
    val hash = kdf.hash(value, salt)
}
