Constants

	// MaxPlaintextSize is set to 64 MB, which is a fairly generous limit. The implementation in x/crypto/xchacha20poly1305 has a plaintext limit to 256 GB.
	// We generally only handle data that is stored within a cookie or a session store, i.e. it should be reasonably small.
	// In most cases the data is around 4 KB or less, mostly depending on the length of the tokens returned from the identity provider.
