Function deriveBytes

deriveBytes(
    base: Uint8Array<ArrayBufferLike>,
    domain: Uint8Array<ArrayBufferLike>,
    byteLength: number,
): Promise<Uint8Array<ArrayBuffer>>
Derives deterministic, domain-separated bytes with HKDF-SHA-256.

The same base, domain, and byteLength always produce the same bytes. Use a distinct domain for each purpose so one base value can safely feed independent derivation contexts. The inputs are not modified.
Parameters
- base: Uint8Array<ArrayBufferLike>
  Salt that namespaces the derivation under a base value.
- domain: Uint8Array<ArrayBufferLike>
  HKDF context information identifying the derived value's use.
- byteLength: number
  Number of output bytes to derive.
Returns Promise<Uint8Array<ArrayBuffer>>
A promise that resolves to exactly byteLength derived bytes.
Throws
A DOMException when Web Crypto rejects an unsupported or invalid derivation request, including an invalid output length.
Example: Derive a 32-byte key for one application domain.
```
const encoder = new TextEncoder()
const bytes = await deriveBytes(
  encoder.encode('account-1'),
  encoder.encode('profile-encryption'),
  32
)
```
