random
Returns a sequence of secure random bytes in a variety of formats
- randomAsBuffer Creates a Buffer filled with random bytes.
- randomAsHex Creates a hex string filled with random bytes.
- randomAsNumber Creates a random number from random bytes.
- randomAsU8a Creates a Uint8Array filled with random bytes.
randomAsBuffer
Creates a Buffer filled with random bytes.
randomAsBuffer (length?: number = 32): Buffer
Returns a Buffer with the specified (optional) length filled with random bytes.
import { randomAsBuffer } from '@polkadot/util-crypto';
randomAsBuffer() // => Buffer([...])
randomAsHex
Creates a hex string filled with random bytes.
randomAsHex (length?: number = 32): string
Returns a hex string with the specified (optional) length filled with random bytes.
import { randomAsHex } from '@polkadot/util-crypto';
randomAsHex() // => 0x...
randomAsNumber
Creates a random number from random bytes.
randomAsNumber (): number
Returns a random number generated from the secure bytes.
import { randomAsNumber } from '@polkadot/util-crypto';
randomAsNumber() // => <random number>
randomAsU8a
Creates a Uint8Array filled with random bytes.
randomAsU8a (length?: number = 32): Uint8Array
Returns a Uint8Array with the specified (optional) length filled with random bytes.
import { randomAsU8a } from '@polkadot/util-crypto';
randomAsU8s() // => Uint8Array([...])
