# Class: Hash

[@nimiq/core](../globals) / Hash

Defined in: @nimiq/core/types/wasm/web.d.ts:1387

## Methods

### [dispose]()

> **[dispose]**(): `void`

Defined in: @nimiq/core/types/wasm/web.d.ts:1390

#### Returns

`void`

---

### free()

> **free**(): `void`

Defined in: @nimiq/core/types/wasm/web.d.ts:1389

#### Returns

`void`

---

### computeBlake2b()

> `static` **computeBlake2b**(`data`): `Uint8Array`

Defined in: @nimiq/core/types/wasm/web.d.ts:1398

Computes a 32-byte <span>

Blake2b

</span>

 hash from the input data.

Blake2b is used for example to compute a public key's address.

#### Parameters

##### data

`Uint8Array`

#### Returns

`Uint8Array`

---

### computeNimiqArgon2d()

> `static` **computeNimiqArgon2d**(`password`, `salt`, `iterations`, `derived_key_length`): `Uint8Array`

Defined in: @nimiq/core/types/wasm/web.d.ts:1411

Computes an <span>

Argon2d

</span>

 hash with some Nimiq-specific parameters.

`iterations` specifies the number of iterations done in the hash
function. It can be used to control the hash computation time.
Increasing this will make it harder for an attacker to brute-force the
password.

`derived_key_length` specifies the number of bytes that are output.

#### Parameters

##### password

`Uint8Array`

##### salt

`Uint8Array`

##### iterations

`number`

##### derived_key_length

`number`

#### Returns

`Uint8Array`

---

### computeNimiqArgon2id()

> `static` **computeNimiqArgon2id**(`password`, `salt`, `iterations`, `derived_key_length`): `Uint8Array`

Defined in: @nimiq/core/types/wasm/web.d.ts:1424

Computes an <span>

Argon2id

</span>

 hash with some Nimiq-specific parameters.

`iterations` specifies the number of iterations done in the hash
function. It can be used to control the hash computation time.
Increasing this will make it harder for an attacker to brute-force the
password.

`derived_key_length` specifies the number of bytes that are output.

#### Parameters

##### password

`Uint8Array`

##### salt

`Uint8Array`

##### iterations

`number`

##### derived_key_length

`number`

#### Returns

`Uint8Array`

---

### computeSha256()

> `static` **computeSha256**(`data`): `Uint8Array`

Defined in: @nimiq/core/types/wasm/web.d.ts:1430

Computes a 32-byte <span>

SHA256

</span>

 hash from the input data.

#### Parameters

##### data

`Uint8Array`

#### Returns

`Uint8Array`

---

### computeSha512()

> `static` **computeSha512**(`data`): `Uint8Array`

Defined in: @nimiq/core/types/wasm/web.d.ts:1436

Computes a 64-byte <span>

SHA512

</span>

 hash from the input data.

#### Parameters

##### data

`Uint8Array`

#### Returns

`Uint8Array`
