Function: toBigEndianKeyId()

function toBigEndianKeyId(keyId): ArrayBuffer;

Defined in: playready/toBigEndianKeyId.ts:12

Converts a 16-byte key ID from little-endian to big-endian format.

Parameters

keyId

ArrayBuffer

The little-endian key ID to convert.

Returns

ArrayBuffer

The big-endian representation of the key ID.

Example

const littleEndianKeyId = 'a0564af7-60c2-d94b-9610-c7ae70d5d970'
const expectedBigEndianKeyId = 'f74a56a0-c260-4bd9-9610-c7ae70d5d970'

const inputBuffer = uuidToArrayBuffer(littleEndianKeyId)
const result = toBigEndianKeyId(inputBuffer)
const resultHex = arrayBufferToUuid(result)

equal(resultHex, expectedBigEndianKeyId)
