Generating Random Data

Bindings for the random data generation API. See the libsodium randombytes docs for more information.

Constants

Buffer lengths (integer)

• randombytes_SEEDBYTES

---

randombytes_random

var uint32 = sodium.randombytes_random() 

Generates a random 32-bit unsigned integer [0, 0xffffffff] (both inclusive).

---

randombytes_uniform

var uint = sodium.randombytes_uniform(upper_bound)

Generates a random 32-bit unsigned integer [0, upper_bound) (last exclusive).

• upper_bound must be at most 0xffffffff

---

randombytes_buf

sodium.randombytes_buf(buf)

Fills buf with random data.

---

randombytes_buf_deterministic

sodium.randombytes_buf_deterministic(buf, seed)

Fills buf with random data, generated from seed.

• seed must be a buffer of length at least randombytes_SEEDBYTES
