Why does SubtleCrypto.verify return an ArrayBuffer?

[dominictobias-bullish]

Hi,

Why does SubtleCrypto.verify return an ArrayBuffer instead of a boolean as per https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto/verify

async verify(
    algorithm: SubtleAlgorithm,
    key: CryptoKey,
    signature: BufferLike,
    data: BufferLike,
  ): Promise<ArrayBuffer> {
    return signVerify(algorithm, key, data, signature) as ArrayBuffer;
  }

And how do we check from this buffer that the signature is valid in this case? Is it simply something like "if the buffer is defined it's valid"?

P.S. Thanks for your amazing work in saving the RN community from the woeful lack of crypto support ❤️
