Function deriveKeyFromPassphrase

deriveKeyFromPassphrase(
    passphrase: string,
    saltU8: Uint8Array,
    iterations?: number,
): Promise<CryptoKey>
Derive an AES-GCM key from a textual passphrase using PBKDF2-SHA256.
Parameters
- passphrase: string
  The passphrase to derive the key from.
- saltU8: Uint8Array
  Salt bytes used during derivation (must match when re-deriving).
- iterations: number = PBKDF2_ITERATIONS
  Optional iteration count (defaults to PBKDF2_ITERATIONS).
Returns Promise<CryptoKey>
The derived AES-GCM CryptoKey.
