CRC Checksums

createCrypto

Create a CRC checksum instance. The result uses little-endian byte order.

| algorithmId | Description | API_LEVEL | | ----------- | -------------- | --------- | --- | | alg.CRC16 | CRC16 checksum | 3.0 | | alg.CRC32 | CRC32 checksum | 3.0 | . |

Type

function createCrypto(algorithmId: typeof alg.CRC16 | typeof alg.CRC32): CRCCrypto | undefined

Parameters

CRCData

Type	Description
number[]|ArrayBuffer|Uint8Array	Data to checksum

CRCCrypto

CRC16/CRC32 checksum instance supporting only encrypt().

Methods

encrypt

Calculate a CRC checksum in little-endian form

encrypt(data: createCrypto.CRCData): CRCResult | undefined

CRCResult

Property	Type	Description
data	ArrayBuffer	CRC checksum in little-endian form
length	number	Data length

Example

import { alg, createCrypto } from '@zos/crypto'

const crc16 = createCrypto(alg.CRC16)
if (!crc16) throw new Error('Failed to create CRC16 instance')
const crc16Result = crc16.encrypt([1, 2, 3])

const crc32 = createCrypto(alg.CRC32)
if (!crc32) throw new Error('Failed to create CRC32 instance')
const crc32Result = crc32.encrypt(new Uint8Array([1, 2, 3]))
