## Hash and verify the passwords { #hash-and-verify-the-passwords }

Import the tools we need from `pwdlib`.

Create a PasswordHash instance with recommended settings - it will be used for hashing and verifying passwords.

/// tip

pwdlib also supports the bcrypt hashing algorithm but does not include legacy algorithms - for working with outdated hashes, it is recommended to use the passlib library.

 *
 * <h3>Providing input to a hash function</h3>
 *
 * <p>The primary way to provide the data that your hash function should act on is via a {@link
 * Hasher}. Obtain a new hasher from the hash function using {@link #newHasher}, "push" the relevant
 * data into it using methods like {@link Hasher#putBytes(byte[])}, and finally ask for the {@code
 * HashCode} when finished using {@link Hasher#hash}. (See an {@linkplain #newHasher example} of

        // This test uses a real MD5 instance to verify the HMAC calculation logic
        // HMACT64 is a modified HMAC-MD5 where the key is truncated at 64 bytes
        // instead of being hashed when it exceeds the block size.

        byte[] key = { (byte) 0x0b, (byte) 0x0b, (byte) 0x0b, (byte) 0x0b, (byte) 0x0b, (byte) 0x0b, (byte) 0x0b, (byte) 0x0b, (byte) 0x0b,

	diskCount := 0
	for _, disk := range disks {
		if disk == nil {
			continue
		}
		diskCount++
	}
	return diskCount
}

// hashOrder - hashes input key to return consistent
// hashed integer slice. Returned integer order is salted
// with an input key. This results in consistent order.
// NOTE: collisions are fine, we are not looking for uniqueness
// in the slices returned.

   *   <li>If the IPv6 address contains an embedded IPv4 address, the function hashes that.
   *   <li>Otherwise, it hashes the upper 64 bits of the IPv6 address.
   * </ul>
   *
   * <p>A "coerced" IPv4 address is equivalent to itself.
   *
   * <p>NOTE: This method is failsafe for security purposes: ALL IPv6 addresses (except localhost
   * (::1)) are hashed to avoid the security risk associated with extracting an embedded IPv4
