The spec never mentions the possibility for the `hash` member of
`RsaHashedKeyAlgorithm` to be a string, it should be a `KeyAlgorithm`
object containing a `name` string member.
Spec: https://w3c.github.io/webcrypto/#dfn-RsaHashedKeyAlgorithm
It is the responsibility of code that deals with TypedArrays to apply
the byte offset and byte length. Not doing this caused Unity Web to
crash, as they call getRandomValues with views into their full main
memory. Previously, it would fill their entire memory of about 33.5 MB
with random bytes.
Previously, callers were passing the size in bytes, but the method
expected bits. This caused a crash in LibCrypto when verifying the key
size later on.
Also make the naming of local variables and parameters a little more
clear between the different AES algorithms :^)
This patch implements and tests window.crypto.sublte.generateKey with
an RSA-OAEP algorithm. In order for the types to be happy, the
KeyAlgorithms objects are moved to their own .h/.cpp pair, and the new
KeyAlgorithms for RSA are added there.
