The little-endian key ID to convert.
The big-endian representation of the key ID.
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)
Converts a 16-byte key ID from little-endian to big-endian format.
