// META: title=WebCryptoAPI: BufferSource arguments and members reject shared buffers

// None of the BufferSource arguments of SubtleCrypto, or of the dictionaries it

// takes, are [AllowShared], so a SharedArrayBuffer, or a view onto one, has to

// throw a TypeError.

// See https://github.com/whatwg/html/issues/5380 for why not `new SharedArrayBuffer()`.
